Round 7 — Input & feedback
- H key cycles hints; F1 opens help (conflict resolved)
- N key cancels active Time Attack session
- Hint text distinguishes "draw from stock" vs "recycle waste"
- Forfeit (G) clears AutoCompleteState so chime does not bleed into new deal
- Zen mode timer clears immediately on Z press
- HUD shows recycle count in both draw modes
- Settings scroll position persisted across open/close
Round 8 — Polish & clarity
- Undo unavailable fires "Nothing to undo" toast
- Streak-break toast on forfeit/abandon when streak > 1
- F11 fullscreen toggle with toast; documented in help and home screens
- H-after-win, new-game countdown expiry, Tab-no-cards toasts
- Win cascade duration/stagger scales with animation speed setting
- Draw-Three cycle counter HUD ("Cycle: N/3")
- Forfeit requires G×2 confirmation within 3 s (mirrors N key)
Round 9 — Game feel & information
- Escape dismisses game-over/stuck overlay (PausePlugin skips Escape when overlay visible)
- Shake animation on rejected drag before snap-back
- Forfeit countdown cancels when any other key is pressed (U/H/D/Z/Space)
- Tab wrap-around fires "Back to first card" toast
- HUD selection indicator shows active Tab-selected pile in yellow
- Challenge time-limit HUD turns orange < 60s, red < 30s
- Win summary shows XP breakdown (+50 base, +25 no-undo, +N speed)
- Game-over overlay: "No more moves available" with clear N/Escape/G instructions

leaderboard_plugin: format_secs was missing the 60-second crossing
boundary (1:00 vs 60s), the zero case (0s), and leading-zero padding
verification (1:05 not 1:5).
pause_plugin: added third-press test confirming the Esc toggle is
symmetric across multiple pause/resume cycles.

Press L to open a leaderboard overlay. On open, an async fetch is
dispatched against the active SyncProvider. Results cache in
LeaderboardResource; the panel rebuilds live when data arrives.
Closing during a fetch is safe (ClosedThisFrame flag prevents
re-spawning the panel in the same frame as the user's despawn command).
Format: ranked table with player name, best score, and fastest win time.
Non-authenticated / LocalOnly providers return an empty list gracefully.
- solitaire_data: add fetch_leaderboard() to SyncProvider trait
(default → Ok([])) and implement in SolitaireServerClient
- solitaire_engine: new LeaderboardPlugin with 5 unit tests
- solitaire_app: register LeaderboardPlugin
