decisions:

- Space bar discover step uses hardcoded German text (not getLetterIntro) to guarantee ␣ symbol mention

# Quick Task 260329-ten: Leertaste Symbol in Entdecken-Phase Summary
|
||
|
|
|
||
|
|
**One-liner:** Added dedicated space bar discover step showing ␣ symbol with "Leertaste" label and child-friendly explanation before practice begins.
|
||
|
|
|
||
|
|
## What Was Done
|
||
|
|
|
||
|
|
The `runDiscoverPhase()` function in `src/ui/screens.ts` previously skipped the space key entirely with `if (key === " ") continue`. This meant children encountered the ␣ symbol during practice without any introduction.
|
||
|
|
|
||
|
|
The fix replaces the skip with a full discover step for the space bar:
|
||
|
|
|
||
|
|
1. Companion text explains the ␣ symbol in child-friendly German: "Siehst du die grosse Taste ganz unten? Das ist die Leertaste! Wenn du dieses Zeichen siehst: ␣ — dann drueckst du mit dem Daumen die Leertaste. Probier es aus!"
|
||
|
|
2. The ␣ symbol (U+2423) is displayed large using the `falling-letter` class, with a "Leertaste" label underneath.
|
||
|
|
3. The space key on the keyboard is highlighted and pulses with `keyboard__key--discover-pulse`.
|
||
|
|
4. Child must press the space bar once to confirm understanding and advance.
|
||
|
|
|
||
|
|
