Extend the launcher design specification and prototype reference with the
"Call to Play" multiplayer coordination feature and clean up top-bar chrome.
Key additions and changes:
- Spec & Roadmap: Document Call to Play mechanics in SPEC.md, including Play
Now / Scheduled call flavors, 15-minute check-in windows, top-bar button
with active count badge, quick-bar ticker stack above grid, overlay modal,
and per-call group chat. Update design/README.md.
- Components & Logic: Add calltoplay.jsx and ctp-chat.jsx components for call
creation, status progression, and chat. Extend data.jsx with a mock peer
roster (PEERS) and helper functions for peer install count tracking.
- Top-bar Cleanup: Move game-folder configuration from top bar into Settings ->
Library, freeing top-bar space for the Call to Play action button.
- Styling & Layout: Add CTP quick-bar, ticker, badge, card, and chat styles to
styles.css, and integrate CTP components into launcher.jsx, components.jsx,
and SoftLAN Launcher.html.
Test Plan:
- `git diff --cached --check` -- passed (no trailing whitespace or conflict markers)
- `cargo check --workspace` -- passed cleanly
- Manual review of staged diff across 9 design/launcher files -- confirmed clean staging
