+Create the config loader and isomorphic Gemini API client with text generation, image generation, retry logic, and rate-limiting.
+
+Purpose: This is the foundation for all AI-powered features. Everything in Phase 2 depends on a working, tested Gemini API client.
+Output: `src/api/config.ts`, `src/api/gemini.ts` with full test coverage.

+
+
+ Task 1: Config loader and Gemini API client with tests (TDD)
+ src/api/config.ts, src/api/config.test.ts, src/api/gemini.ts, src/api/gemini.test.ts, src/types.ts, src/storage/db.ts
+
+ - src/types.ts (existing interfaces — extend Settings with apiCallsToday + lastApiCallDate per D-03)
+ - src/storage/db.ts (existing DB methods — pattern to follow)
+ - public/config.json (actual config structure: geminiApiKey, geminiModel, imageModel)
+ - SPEC.md sections 6.4 and 9.1 (API endpoints and config format)
+
+
+ Config loader (src/api/config.ts):
+ - Test: loadConfig() returns GeminiConfig with geminiApiKey, geminiModel, imageModel
+ - Test: loadConfig() returns null when fetch fails (e.g. 404)
+ - Test: loadConfig() returns null when JSON is malformed
+ - Test: loadConfig() caches result after first successful call (does not re-fetch)
+
+ Gemini text client (src/api/gemini.ts — generateText):
+ - Test: generateText returns extracted text from Gemini response
+ - Test: generateText retries on 500 error up to 3 times with backoff
+ - Test: generateText returns null after 3 failed attempts
+ - Test: generateText sends correct request body (model, contents with systemInstruction)
+
+ Gemini image client (src/api/gemini.ts — generateImage):
+ - Test: generateImage returns Blob from base64 image in Gemini response
+ - Test: generateImage sends reference images as inlineData parts
+ - Test: generateImage sets response_modalities to ["IMAGE"] in generationConfig
+ - Test: generateImage returns null on failure
+
+ Rate-limiting:
+ - Test: checkRateLimit returns true when under limit (0 calls today)
+ - Test: checkRateLimit returns false when at limit (1 image + 1 text today)
+ - Test: incrementApiCall increments correct counter
+ - Test: rate limit resets when lastApiCallDate differs from today
+
+
+ **Step 1: Extend Settings type (per D-03)**
+ In `src/types.ts`, add to `Settings` interface:
+ ```typescript
+ apiCallsToday: { text: number; image: number };
+ lastApiCallDate: string; // ISO date "YYYY-MM-DD"
+ ```
+
+ **Step 2: Create src/api/config.ts (per D-07, GAPI-01)**
+ ```typescript
+ export interface GeminiConfig {
+ geminiApiKey: string;
+ geminiModel: string; // e.g. "gemini-2.5-flash"
+ imageModel: string; // e.g. "gemini-3.1-flash-preview-image"
+ }
+
+ let cachedConfig: GeminiConfig | null = null;
+
+ export async function loadConfig(): Promise {
+ if (cachedConfig) return cachedConfig;
+ try {
+ const res = await fetch('/config.json');
+ if (!res.ok) return null;
+ const data = await res.json();
+ if (!data.geminiApiKey || !data.geminiModel || !data.imageModel) return null;
+ cachedConfig = data as GeminiConfig;
+ return cachedConfig;
+ } catch {
+ return null;
+ }
+ }
+
+ // For Node.js usage in build script (per D-01)
+ export function loadConfigFromObject(obj: GeminiConfig): void {
+ cachedConfig = obj;
+ }
+
+ export function resetConfigCache(): void {
+ cachedConfig = null;
+ }
+ ```
+
+ **Step 3: Create src/api/gemini.ts (per D-07, D-08, D-09, D-10)**
+ - `generateText(prompt: string, systemPrompt: string, config: GeminiConfig): Promise`
+ - POST to `https://generativelanguage.googleapis.com/v1beta/models/${config.geminiModel}:generateContent?key=${config.geminiApiKey}`
+ - Body: `{ contents: [{ role: "user", parts: [{ text: prompt }] }], systemInstruction: { parts: [{ text: systemPrompt }] } }`
+ - Extract `response.candidates[0].content.parts[0].text`
+ - Retry 3 times with delays [1000, 2000, 4000] ms on non-2xx responses (per D-09)
+ - Return null on final failure
+
+ - `generateImage(prompt: string, referenceImages: Blob[], config: GeminiConfig): Promise`
+ - POST to `https://generativelanguage.googleapis.com/v1beta/models/${config.imageModel}:generateContent?key=${config.geminiApiKey}`
+ - Build parts array: for each referenceImage, convert to base64 and add as `{ inlineData: { mimeType: "image/png", data: base64 } }`, then add text part with prompt (per D-08)
+ - generationConfig: `{ responseModalities: ["IMAGE"] }`
+ - Extract base64 image from `response.candidates[0].content.parts[0].inlineData.data`
+ - Convert base64 to Blob and return
+ - Return null on failure (no retry for image — too expensive)
+
+ - Rate-limiting helpers (per D-10, GAPI-06):
+ ```typescript
+ export async function checkRateLimit(db: IDBDatabase, type: 'text' | 'image'): Promise
+ export async function incrementApiCall(db: IDBDatabase, type: 'text' | 'image'): Promise
+ ```
+ - Check `settings.lastApiCallDate` — if different from today, reset counts to 0
+ - Max 1 image + 1 text per exercise unit (check `apiCallsToday.text < 1` or `apiCallsToday.image < 1`)
+
+ **Step 4: Write tests**
+ - Use `vi.fn()` and `vi.spyOn(globalThis, 'fetch')` to mock fetch calls
+ - Use `fake-indexeddb` for rate-limit tests (already in devDeps)
+ - Test config loader with mocked fetch responses
+ - Test generateText with mocked Gemini responses
+ - Test generateImage with mocked responses containing base64 image data
+ - Test retry logic by failing first 2 calls then succeeding
+ - Test rate-limit read/write/reset cycle
+
+ **Follow TDD cycle:** Write all tests first (RED), then implement (GREEN), then refactor.
+
+
+ cd /home/dev/workspace/zauberwald && npx vitest run src/api/

+ - `grep "lastApiCallDate" src/types.ts` matches (Settings extended per D-03)
+ - `npx vitest run src/api/` passes with 0 failures
+ - At least 10 test cases across config.test.ts and gemini.test.ts
+
+ Config loader fetches/caches config.json. generateText sends correct Gemini REST request with retry (3x exponential backoff). generateImage sends reference images as base64 inlineData with response_modalities: ["IMAGE"]. Rate-limiting checks and increments counters in Settings store with daily reset. All tests pass.

+ - src/game/levels.ts (exact keys per level for letter introductions)
+ - SPEC.md section 9.2 (prompt templates — model the tone of fallback texts after these)
+
+
+ Create `src/companion/fallbacks.ts` with the following exports (per D-11, GAPI-04):
+
+ **1. Fallback greetings** — 10 entries, keyed by time of day:
+ ```typescript
+ export type TimeOfDay = 'morgen' | 'mittag' | 'abend';
+
+ export interface FallbackGreeting {
+ text: string;
+ timeOfDay: TimeOfDay | 'any';

+ // Example: { text: "Guten Morgen! Der Wald hat auf dich gewartet.", timeOfDay: "morgen" }
+ ];
+ ```
+
+ Rules for ALL texts (per COMP-04):
+ - Max 25 words per text
+ - Simple German a 7-year-old can read
+ - No performance praise ("toll gemacht", "super", etc.)
+ - No English words
+ - Warm, friendly, nature-themed
+
+ **2. Fallback forest comments** — 10 entries:
+ ```typescript
+ export const fallbackForestComments: string[] = [
+ // Express wonder and joy about new forest elements
+ // Example: "Oh schau mal! Ein neuer Bewohner ist in unseren Wald gezogen!"
+ ];
+ ```
+
+ **3. Fallback letter introductions** — one per key in levels 1-6:
+ ```typescript
+ export interface LetterIntro {
+ letter: string;
+ finger: string; // e.g. "linker Zeigefinger"
+ text: string; // The mnemonic/introduction text
+ }
+
+ export const fallbackLetterIntros: LetterIntro[] = [
+ // Level 1
+ { letter: "f", finger: "linker Zeigefinger", text: "Das F ist da, wo dein linker Zeigefinger zu Hause ist. Spuerst du den kleinen Huegel?" },
+ { letter: "j", finger: "rechter Zeigefinger", text: "Das J hat einen kleinen Strich unten. Dein rechter Zeigefinger findet ihn sofort!" },
+ { letter: " ", finger: "Daumen", text: "Die grosse Leertaste ganz unten drueckst du mit dem Daumen. Einfach druecken!" },
+ // Level 2: D (linker Mittelfinger), K (rechter Mittelfinger)
+ // Level 3: S (linker Ringfinger), L (rechter Ringfinger)
+ // Level 4: A (linker kleiner Finger), Ö (rechter kleiner Finger)
+ // Level 5: G (linker Zeigefinger Mitte), H (rechter Zeigefinger Mitte)
+ // Level 6: E (linker Mittelfinger oben), I (rechter Mittelfinger oben)
+ // Use nature/forest-themed mnemonics for each letter
+ ];
+ ```
+
+ **4. Helper function to get fallback:**
+ ```typescript
+ export function getRandomFallbackGreeting(timeOfDay: TimeOfDay): string
+ export function getRandomFallbackForestComment(): string
+ export function getFallbackLetterIntro(letter: string): LetterIntro | undefined
+ ```
+
+ Write all 10 greetings, all 10 forest comments, and all letter intros for F, J, Space, D, K, S, L, A, OE, G, H, E, I (13 entries). All in German, all max 25 words.

+
+ - SPEC.md section 5.1 (visual style: watercolor, pastel, warm)
+ - SPEC.md section 7.2 (color palette CSS custom properties)
+ - src/styles/main.css (existing color values to match)
+
+
+ Create 7 SVG fallback images in `src/assets/fallback-images/` (per D-12, GAPI-05):
+
+ Each SVG should be:
+ - 200x200 viewBox
+ - Simple, clean shapes using pastel colors from the palette
+ - Watercolor-inspired: soft gradients, rounded shapes, no hard edges
+ - Child-friendly, warm aesthetic
+ - No text in the images
+
+ Colors to use (from SPEC.md palette):
+ - Greens: #6DB87D, #E8F5E4
+ - Pink: #E88BAE
+ - Purple: #9B7DC4
+ - Blue: #7DB8D4
+ - Gold: #E8B84B
+ - Cream: #FFF8F0
+
+ Files to create:
+ 1. `blume.svg` — A simple flower with rounded petals (pink/purple)
+ 2. `pilz.svg` — A mushroom with red cap and white dots (classic fairy tale)
+ 3. `vogel.svg` — A small bird (blue/green)
+ 4. `schmetterling.svg` — A butterfly with pastel wings
+ 5. `reh.svg` — A young deer (simple silhouette, warm brown)
+ 6. `baum.svg` — A small magical tree with round crown
+ 7. `bach.svg` — A small stream with stones (blue tones)
+
+ Each SVG should use `` with radial or linear gradients for the watercolor feel. Use `opacity` and `filter` for softness where appropriate. Keep SVGs under 3KB each for performance.
+
+ Also create an index file for easy imports:
+ This is NOT needed — Vite handles static imports. The fallback images will be referenced by path in the companion module (Plan 04).
+
+
+ cd /home/dev/workspace/zauberwald && ls src/assets/fallback-images/*.svg | wc -l
+
+
+ - `ls src/assets/fallback-images/*.svg | wc -l` returns 7
+ - Each SVG file starts with `
+ 7 SVG fallback images exist in src/assets/fallback-images/, each depicting a forest element in pastel watercolor style, all under 5KB, no text.
+
+
+
+
+
+- `npx tsx -e "import { fallbackGreetings } from './src/companion/fallbacks'; console.log(fallbackGreetings.length)"` outputs >= 10
+- `ls src/assets/fallback-images/*.svg | wc -l` outputs 7
+
+
+
+- Fallback texts module has 10 greetings, 10 forest comments, 13 letter intros — all German, max 25 words
+- 7 SVG fallback images depict forest elements in pastel watercolor style
+- All content is child-appropriate and matches the Zauberwald aesthetic

+
+ Task 1: Add IndexedDB accessor methods for remaining stores
+ src/storage/db.ts
+
+ - src/storage/db.ts (current code with getProgress/saveProgress/getSettings/saveSettings pattern)
+ - src/types.ts (CompanionAssets, StyleReference, ForestElement interfaces)
+
+
+ Add the following methods to `src/storage/db.ts` following the existing Promise-wrapped pattern (per D-04):
+
+ **companionAssets store** (keyed by characterType):
+ ```typescript
+ export function saveCompanionAssets(db: IDBDatabase, assets: CompanionAssets): Promise
+ // Same pattern as saveProgress — tx "readwrite", store.put(assets)
+
+ export function getCompanionAssets(db: IDBDatabase, characterType: CompanionType): Promise
+ // Same pattern as getProgress — tx "readonly", store.get(characterType)
+ ```
+
+ **styleReference store** (singleton, id: 1):
+ ```typescript
+ export function saveStyleReference(db: IDBDatabase, ref: StyleReference): Promise
+ // store.put(ref) — same as saveSettings pattern
+
+ export function getStyleReference(db: IDBDatabase): Promise
+ // store.get(1) — same as getSettings pattern
+ ```
+
+ **forestElements store** (auto-increment):
+ ```typescript
+ export function saveForestElement(db: IDBDatabase, element: ForestElement): Promise
+ // store.add(element), return request.result as number (the auto-incremented id)
+
+ export function getForestElements(db: IDBDatabase): Promise
+ // store.getAll(), return result as ForestElement[]
+ ```
+
+ Add required imports at top: `import type { CompanionAssets, CompanionType, ForestElement, StyleReference } from "../types";`
+ (Keep existing Progress and Settings imports.)
+
+
+ cd /home/dev/workspace/zauberwald && npx tsx -e "import { saveCompanionAssets, getCompanionAssets, saveStyleReference, getStyleReference, saveForestElement, getForestElements } from './src/storage/db'; console.log('All 6 methods exported OK')"
+
+
+ - `grep -c "export function saveCompanionAssets" src/storage/db.ts` returns 1
+ - `grep -c "export function getCompanionAssets" src/storage/db.ts` returns 1
+ - `grep -c "export function saveStyleReference" src/storage/db.ts` returns 1
+ - `grep -c "export function getStyleReference" src/storage/db.ts` returns 1
+ - `grep -c "export function saveForestElement" src/storage/db.ts` returns 1
+ - `grep -c "export function getForestElements" src/storage/db.ts` returns 1
+ - `grep "CompanionAssets\|CompanionType\|ForestElement\|StyleReference" src/storage/db.ts | head -1` shows the types imported
+
+ All 6 new IndexedDB accessor methods added to db.ts — saveCompanionAssets, getCompanionAssets, saveStyleReference, getStyleReference, saveForestElement, getForestElements — following existing Promise-wrapped pattern.
+
+
+
+ Task 2: Build script for asset generation + run it
+ scripts/generate-assets.ts, package.json
+
+ - src/api/gemini.ts (generateImage function signature from Plan 01)
+ - src/api/config.ts (GeminiConfig interface, loadConfigFromObject)
+ - src/companion/characters.ts (companion definitions — 4 companions with type, name, personality)
+ - SPEC.md section 9.2 (Character Sheet prompt, Avatar prompt, visual descriptions per character)
+ - SPEC.md section 14.2 (asset generation flow)
+ - public/config.json (actual config file path)
+
+
+ **Step 1: Add tsx devDependency and npm script**
+ In `package.json`, add to devDependencies: `"tsx": "^4.0.0"`
+ Add script: `"generate-assets": "tsx scripts/generate-assets.ts"`
+ Run `npm install` after editing.
+
+ **Step 2: Create `scripts/generate-assets.ts`** (per D-01, D-02, ASST-01)
+
+ The script runs in Node.js via `npx tsx`. It:
+
+ 1. Reads `public/config.json` via `fs.readFileSync('./public/config.json', 'utf-8')` and parses as `GeminiConfig`
+ 2. Uses `loadConfigFromObject()` from `src/api/config.ts` to set the config
+ 3. For each of the 4 companions, generates:
+ a. **Character Sheet** using the prompt from SPEC.md section 9.2:
+ ```
+ Character sheet for a children's book. The character is {name}, {visualDescription}.
+ Show the character in 3 views: front view, side view, and a close-up of the face.
+ All views must show the EXACT SAME character with identical colors, proportions, and features.
+ Art style: Watercolor children's book illustration, warm pastel colors, soft edges, magical forest theme. White background.
+ Label each view clearly: "FRONT" "SIDE" "FACE"
+ The character must be: cute, friendly, approachable, with large expressive eyes. Suitable for a 7-year-old audience.
+ ```
+ b. **Avatar** using the character sheet as reference image:
+ ```
+ Create a single portrait of this exact character from the reference sheet.
+ Show only the face and upper body, looking directly at the viewer with a warm, friendly expression.
+ Same art style as the reference. Square format. No text. No background (or simple soft gradient).
+ ```
+
+ 4. Generates **Style Reference** — an initial forest scene:
+ ```
+ Watercolor children's book illustration of a magical forest clearing.
+ Warm pastel colors, soft edges, dreamy atmosphere. A gentle meadow surrounded
+ by friendly trees, dappled sunlight, small flowers, and a hint of magic sparkles.
+ No text, no letters, no characters. This sets the visual style for all future forest images.
+ ```
+
+ 5. Saves each file using `fs.writeFileSync`:
+ - `src/assets/companions/fee-lila/character-sheet.png`
+ - `src/assets/companions/fee-lila/avatar.png`
+ - `src/assets/companions/einhorn-stella/character-sheet.png`
+ - `src/assets/companions/einhorn-stella/avatar.png`
+ - `src/assets/companions/fuchs-finn/character-sheet.png`
+ - `src/assets/companions/fuchs-finn/avatar.png`
+ - `src/assets/companions/eule-elsa/character-sheet.png`
+ - `src/assets/companions/eule-elsa/avatar.png`
+ - `src/assets/style-reference/initial-forest-scene.png`
+
+ Visual descriptions per companion (from SPEC.md section 9.2):
+ - fee: "a small fairy with lavender-purple wings, a flowing lilac dress, big warm brown eyes, a tiny flower crown made of forget-me-nots, light skin, and short wavy auburn hair"
+ - einhorn: "a small unicorn with a white coat, a shimmering golden horn, a flowing mane in soft rainbow pastels (pink, lavender, light blue), big dark eyes with long lashes, and small silver hooves"
+ - fuchs: "a young red fox with warm orange-brown fur, a white chest and belly, a bushy tail with a white tip, bright curious amber eyes, and slightly oversized pointed ears"
+ - eule: "a small round owl with soft brown-and-cream feathers, a heart-shaped face, large round golden eyes, tiny ear tufts, and small talons perched on a mossy branch"
+
+ The script should:
+ - Log progress to stdout: "Generating character sheet for {name}..." etc.
+ - Convert Blob responses to Buffer via `blob.arrayBuffer()` then `Buffer.from()`
+ - Handle errors gracefully: if one generation fails, log error and continue with others
+ - Exit with code 1 if any generation failed, 0 if all succeeded
+ - Add a 2-second delay between API calls to avoid rate limiting
+
+ **Step 3: Run the script**
+ Execute `npm run generate-assets` and verify all 9 PNG files are created.
+ If any fail, check the error and retry (the script should be re-runnable).
+
+ **Important:** The `generateImage` function in `src/api/gemini.ts` uses browser `fetch`. Node.js 18+ has native `fetch`, so this should work. If there are issues with `Blob` in Node.js, use `Buffer` and convert. The script may need to use `node:buffer` Blob or polyfill — handle at implementation time.
+
+
+ cd /home/dev/workspace/zauberwald && ls -la src/assets/companions/*/character-sheet.png src/assets/companions/*/avatar.png src/assets/style-reference/initial-forest-scene.png 2>&1 | grep -c ".png"
+
+
+ - `grep "generate-assets" package.json` shows the npm script
+ - `grep "tsx" package.json` shows tsx in devDependencies
+ - `test -f scripts/generate-assets.ts && echo "exists"` returns "exists"
+ - `ls src/assets/companions/fee-lila/character-sheet.png src/assets/companions/fee-lila/avatar.png` succeeds
+ - `ls src/assets/companions/einhorn-stella/character-sheet.png src/assets/companions/einhorn-stella/avatar.png` succeeds
+ - `ls src/assets/companions/fuchs-finn/character-sheet.png src/assets/companions/fuchs-finn/avatar.png` succeeds
+ - `ls src/assets/companions/eule-elsa/character-sheet.png src/assets/companions/eule-elsa/avatar.png` succeeds
+ - `ls src/assets/style-reference/initial-forest-scene.png` succeeds
+ - All 9 PNG files are > 1KB (not empty): `find src/assets -name "*.png" -size +1k | wc -l` returns 9
+
+ Build script generates 4 character sheets + 4 avatars + 1 style reference via Gemini API. All 9 PNG files exist in correct directories and are non-empty. `npm run generate-assets` is a working npm script.
+
+
+
+
+
+- `npm run generate-assets` completes without errors (or re-run successfully)
+- `find src/assets -name "*.png" -size +1k | wc -l` returns 9
+- All 6 new DB methods compile: `npx tsc --noEmit src/storage/db.ts`
+
+
+
+- IndexedDB has accessors for all 5 stores (progress, settings from Phase 1 + companionAssets, styleReference, forestElements new)
+- Build script reads config.json, calls Gemini API, saves 9 PNG files
+- All generated assets are suitable quality (child-friendly watercolor style)

+
+
+Create the companion text module that provides AI-generated or fallback text for greetings, letter introductions, and forest comments.
+
+Purpose: The companion is the emotional core of Zauberwald. This module makes her speak — via AI when possible, via curated fallbacks otherwise.
+Output: `src/companion/companion.ts` with 3 exported functions, full test coverage.

+
+
+
+ Task 1: Add avatar URLs to companion definitions and update welcome screen
+ src/companion/characters.ts, src/ui/screens.ts, src/styles/main.css
+
+ - src/companion/characters.ts (current CompanionDefinition interface and companions array)
+ - src/ui/screens.ts (initWelcomeScreen — renders companion cards with emoji spans)
+ - src/styles/main.css (existing companion-card styles)
+ - src/assets/companions/fee-lila/avatar.png (verify file exists)
+
+
+ **Step 1: Update src/companion/characters.ts** (per D-05)
+
+ Add static imports for each avatar PNG (Vite resolves these to hashed URLs):
+ ```typescript
+ import feeLilaAvatar from "../assets/companions/fee-lila/avatar.png";
+ import einhornStellaAvatar from "../assets/companions/einhorn-stella/avatar.png";
+ import fuchsFinnAvatar from "../assets/companions/fuchs-finn/avatar.png";
+ import euleElsaAvatar from "../assets/companions/eule-elsa/avatar.png";
+ ```
+
+ Extend `CompanionDefinition` interface:
+ ```typescript
+ export interface CompanionDefinition {
+ type: CompanionType;
+ name: string;
+ emoji: string;
+ personality: string;
+ avatarUrl: string; // NEW — Vite-resolved URL to avatar PNG
+ }
+ ```
+
+ Add `avatarUrl` to each companion entry:
+ ```typescript
+ { type: "fee", name: "Lila", emoji: "🧚", personality: "...", avatarUrl: feeLilaAvatar },
+ { type: "einhorn", name: "Stella", emoji: "🦄", personality: "...", avatarUrl: einhornStellaAvatar },
+ { type: "fuchs", name: "Finn", emoji: "🦊", personality: "...", avatarUrl: fuchsFinnAvatar },
+ { type: "eule", name: "Elsa", emoji: "🦉", personality: "...", avatarUrl: euleElsaAvatar },
+ ```
+
+ **Step 2: Update welcome screen in src/ui/screens.ts** (per D-05, D-06, ASST-03)
+
+ In `initWelcomeScreen`, change the card innerHTML from emoji to img with onerror fallback:
+
+ Replace:
+ ```typescript
+ card.innerHTML = `
+ ${c.emoji}
+ ${c.name}
+ `;
+ ```
+
+ With:
+ ```typescript
+ card.innerHTML = `
+ 
+ ${c.emoji}
+ ${c.name}
+ `;
+ ```
+
+ Per D-06: If the img fails to load, the onerror handler hides the img and shows the emoji fallback.
+
+ **Step 3: Add CSS for avatar images in src/styles/main.css**
+
+ Add after existing `.companion-card__emoji` styles:
+ ```css
+ .companion-card__avatar {
+ width: 80px;
+ height: 80px;
+ border-radius: 50%;
+ object-fit: cover;
+ margin-bottom: 0.5rem;
+ }
+ ```
+
+ Also add a companion avatar class for the lesson screen:
+ ```css
+ .companion-area {
+ display: flex;
+ align-items: center;
+ gap: 0.75rem;
+ padding: 0.75rem 1rem;
+ background: var(--bg-cream);
+ border-radius: 1rem;
+ margin-bottom: 1rem;
+ }
+
+ .companion-area__avatar {
+ width: 48px;
+ height: 48px;
+ border-radius: 50%;
+ object-fit: cover;
+ flex-shrink: 0;
+ }
+
+ .companion-area__text {
+ font-family: 'Nunito', sans-serif;
+ font-size: 1rem;
+ color: var(--text-warm);
+ line-height: 1.4;
+ }
+ ```
+
+
+ cd /home/dev/workspace/zauberwald && grep -c "avatarUrl" src/companion/characters.ts && grep -c "companion-card__avatar" src/ui/screens.ts && grep -c "companion-card__avatar" src/styles/main.css
+
+
+ - `grep "avatarUrl: string" src/companion/characters.ts` matches (interface extended)
+ - `grep -c "import.*avatar.*from" src/companion/characters.ts` returns 4 (one per companion)
+ - `grep "companion-card__avatar" src/ui/screens.ts` shows img element used in card
+ - `grep "onerror" src/ui/screens.ts` shows fallback handler (per D-06)
+ - `grep "companion-card__avatar" src/styles/main.css` shows avatar styling
+ - `grep "companion-area" src/styles/main.css` shows companion area styling for lesson screen
+
+ Welcome screen renders avatar PNGs with emoji fallback on error. CompanionDefinition has avatarUrl field. CSS styles avatar images at 80px round in cards, 48px round in companion area.
+
+
+
+ Task 2: Add companion greeting to forest screen and avatar to lesson screen
+ src/app.ts, src/ui/screens.ts, index.html
+
+ - src/app.ts (initApp flow — returning user goes to forest screen)
+ - src/ui/screens.ts (initLessonScreen — current lesson screen setup)
+ - src/forest/scene.ts (initForestScreen — how forest screen is initialized)
+ - src/companion/companion.ts (getGreeting function from Plan 04)
+ - src/companion/characters.ts (updated with avatarUrl from Task 1)
+ - index.html (current HTML structure for all screens)
+
+
+ **Step 1: Add companion greeting area to forest screen** (per D-14, COMP-01)
+
+ In `index.html`, inside `screen-forest` div, add a greeting container before the level grid:
+ ```html
+
+
![]()
+
+
+
![]()
+
