feat(player): Feldenkrais rest-button for lesson audio player

## Plan Deliver the **"Lesson player (rest-button)"** Core Platform item — make rest a first-class, nurturing action in the lesson audio player, honouring the Feldenkrais principle that rest is *part of* the lesson, not an interruption. ## Outcome - `src/components/RestOverlay.tsx` — a `role="dialog"` overlay with a welcoming, non-pressuring message (**"Ruhe, solange du möchtest. Es gibt nichts zu erreichen."** — no countdown, no goal language). Parent-controlled. - `AudioPlayer.tsx` — new **"Rest" button** pauses the audio and shows the overlay; the user continues only when ready (the overlay's resume button simply hides it; the user re-presses play to continue). - **i18n**: 3 new `player.rest_*` keys in all 9 languages (de/en/es/fr/he/pt/pt-BR/ru/zh). The lesson player already had play/pause/seek/resume/speed/loop. The **rest-button was the defining missing piece** that distinguishes an ATM lesson player from a generic audio player. ## Impact on release goals Advances the **Core Platform → "Lesson player (rest-button)"** roadmap item from `[ ]` to `[~]`. Strengthens the habit-loop **routine** leg and the D1→D7 autonomy-supportive experience: the user can rest without guilt and continue without pressure. ## Blackbox - **Unit suite 80/80 green** (12 files), incl. **5 new** tests in `src/components/__tests__/RestOverlay.test.tsx`: 1. renders the nurturing rest message 2. shows a non-pressuring resume button 3. calls `onResume` when clicked 4. accessible: overlay is a `role="dialog"` with a heading 5. **Feldenkrais assertion**: no countdown/timer or strain/obligation language appears - TSC clean. ## Six-perspectives check - [x] **Product:** the rest-button is an observable, demo-able feature; amplifies the felt-change moment. - [x] **Engineering:** minimal diff (additive component + one button + overlay), test-first, no existing behaviour changed. - [x] **Psychology:** autonomy-supportive — rest is welcoming, not penalised; no "you must continue". - [x] **Biomechanics:** rest lets the nervous system integrate (gravity-aligned, no effort). - [x] **Anatomy:** N/A (UI only). - [x] **Feldenkrais:** the core principle "rest whenever you like; there is nothing to reach" is now explicit, with a test asserting no strain language. ## Risk - Minimal — additive component + one button.

Plan

Deliver the "Lesson player (rest-button)" Core Platform item — make rest a first-class, nurturing action in the lesson audio player, honouring the Feldenkrais principle that rest is part of the lesson, not an interruption.

Outcome

src/components/RestOverlay.tsx — a role="dialog" overlay with a welcoming, non-pressuring message ("Ruhe, solange du möchtest. Es gibt nichts zu erreichen." — no countdown, no goal language). Parent-controlled.
AudioPlayer.tsx — new "Rest" button pauses the audio and shows the overlay; the user continues only when ready (the overlay's resume button simply hides it; the user re-presses play to continue).
i18n: 3 new player.rest_* keys in all 9 languages (de/en/es/fr/he/pt/pt-BR/ru/zh).

The lesson player already had play/pause/seek/resume/speed/loop. The rest-button was the defining missing piece that distinguishes an ATM lesson player from a generic audio player.

Impact on release goals

Advances the Core Platform → "Lesson player (rest-button)" roadmap item from [ ] to [~]. Strengthens the habit-loop routine leg and the D1→D7 autonomy-supportive experience: the user can rest without guilt and continue without pressure.

Blackbox

Unit suite 80/80 green (12 files), incl. 5 new tests in src/components/__tests__/RestOverlay.test.tsx:
1. renders the nurturing rest message
2. shows a non-pressuring resume button
3. calls onResume when clicked
4. accessible: overlay is a role="dialog" with a heading
5. Feldenkrais assertion: no countdown/timer or strain/obligation language appears
TSC clean.

Six-perspectives check

Product: the rest-button is an observable, demo-able feature; amplifies the felt-change moment.
Engineering: minimal diff (additive component + one button + overlay), test-first, no existing behaviour changed.
Psychology: autonomy-supportive — rest is welcoming, not penalised; no "you must continue".
Biomechanics: rest lets the nervous system integrate (gravity-aligned, no effort).
Anatomy: N/A (UI only).
Feldenkrais: the core principle "rest whenever you like; there is nothing to reach" is now explicit, with a test asserting no strain language.

Risk

Minimal — additive component + one button. AudioPlayer gains relative positioning for the absolute overlay; no existing behaviour changed. The overlay is purely presentational and parent-controlled.

Checklist

Branch off latest dev
Conventional Commits (test: red-first, feat: implementation)
Patchlog entry appended
Roadmap status updated
No secrets / no large binaries
