Problem: Translation keys flashed for ~500ms before being replaced with
actual translations due to client-side async message loading.
Solution:
- Load messages server-side in layout.tsx before initial render
- Pass initialLocale and initialMessages as props to ClientProviders
- Update LocaleProvider to accept and use server-provided initial values
- Remove client-side useEffect that caused async loading delay
- Export getRequestLocale() function for server-side locale detection
Result: Zero FOUC - translations display instantly on page load while
maintaining instant language switching via changeLocale().

Adds the nativeAbacusNumbers setting that was being used by Rithmomachia
but was never committed, causing CI build failures.
Changes:
- Add nativeAbacusNumbers boolean field to abacus_settings schema
- Add database migration for the new field (default: false)
- Add UI toggle in AbacusDisplayDropdown
- Update AbacusSettingsSync to exclude nativeAbacusNumbers from
abacus-react sync (it's app-specific, not abacus component config)
This setting allows displaying numbers as abaci throughout the app
where practical, used by arcade games like Rithmomachia.
Fixes TypeScript build errors in:
- src/arcade-games/rithmomachia/components/PlayingGuideModal.tsx

Fixed issue where modal would zoom away from cursor when resizing.
**Problem:** The resize logic was accumulating deltas by updating `dragStart`
with calculated offsets, causing exponential growth and the modal to zoom away.
**Solution:** Reset `dragStart` to current mouse position after each resize step.
This makes each delta calculation relative to the current position, not the
original click position.
**Changes:**
- Removed `actualDeltaX` and `actualDeltaY` tracking
- Reset `dragStart` to `{ x: e.clientX, y: e.clientY }` after each resize
- Simplified resize calculation logic
Now resizing works smoothly with cursor following the resize handle correctly.

Applied four critical corrections to match the reference photo:
1. Black Column C (inner edge) - Fixed circle sequence:
- C3: 9 (was 3)
- C4: 7 (was 4)
- C5: 5 (was 2)
- C6: 3 (was 12)
2. White N8 - Fixed top inner triangle:
- N8: T(9) (was T(5))
3. White Pyramid - Moved to lower position:
- O2: Pyramid (was O7)
- Shifted O2-O6 circles down to O3-O7
4. Black A6 - Fixed outer rim piece:
- A6: S(120) (was T(64))
- B6: T(64) (was C(81))
- B7: C(81) (was S(120))
These changes ensure the layout matches the traditional Rithmomachia
reference image with large figurates on outer edges (A, P) and small
geometric units on inner edges (C, N).

Restore all missing white/black player assignment functionality that was
disconnected after git rebase operations.
**Player Assignment UI (reconnected):**
- Wire up assignWhitePlayer and assignBlackPlayer from context
- Pass whitePlayerId, blackPlayerId, onAssignWhitePlayer, onAssignBlackPlayer,
and gamePhase props to PageWithNav
- Enable split [W][B] buttons on hover for unassigned players
- Enable SWAP button on hover for assigned players
- Support observer mode (players not assigned to white/black can spectate)
- Permission system: only host (in rooms) or local players can assign
**Duplicate Indicator Fix:**
- Hide playerBadge pill when assignment UI is active to prevent showing both
the fancy badge AND the assignment buttons
- Keep "Your turn" / "Their turn" labels (working as intended)
**Setup Layout Fix:**
- Add SetupPlayerRequirement panel when tooFew players (styled for medieval theme)
- Hide entire setup config UI when showing player requirement panel
- Prevents squishing/scrolling issues - clean swap between the two UIs
- Panel shows inactive local players, invite codes, and room history
**Navigation Banner:**
- Hide "Need two active players" banner during setup (panel handles this)
- Show banner during playing phase only
All ~10 hours of missing player management work now restored and functional.
