CRITICAL REGRESSION: Production container crash-looping with:
"Error: libc.musl-x86_64.so.1: cannot open shared object file"
Root cause identified:
Commit dafdfdd2 (3D printing support) changed runner stage from:
FROM node:18-alpine → FROM node:18-slim
to add OpenSCAD (not available in Alpine repos).
However, the deps stage was NOT updated and remained Alpine-based,
causing a binary incompatibility:
- deps stage (Alpine/musl) compiles better-sqlite3 for musl libc
- runner stage (Debian/glibc) cannot run musl-compiled binaries
Solution:
Changed deps stage from node:18-alpine to node:18-slim to match
runner, ensuring better-sqlite3 is compiled for the correct target.
Both stages must now use Debian because OpenSCAD is required for
3D printing functionality and is not available in Alpine.

Build errors:
- Route /api/player-stats couldn't be rendered statically because it used `headers`
- Route /api/debug/active-players couldn't be rendered statically because it used `headers`

Add comprehensive preview system for arcade games:
- GamePreview component: Renders any arcade game in preview mode
- MockArcadeEnvironment: Provides isolated context for previews
- MockArcadeHooks: Mock implementations of useArcadeSession, etc.
- MockGameStates: Pre-defined game states for each arcade game
- ViewportContext: Track and respond to viewport size changes
Enables rendering game components outside of arcade rooms for:
- Documentation and guides
- Marketing/showcase pages
- Testing and development
- Game selection interfaces
Mock states include setup, playing, and results phases for all
five arcade games (matching, complement-race, memory-quiz,
card-sorting, rithmomachia).

Implement comprehensive per-player statistics tracking across arcade games:
- Database schema: player_stats table with per-player metrics
- Migration: 0013_add_player_stats.sql for schema deployment
- Type system: Universal GameResult types supporting all game modes
(competitive, cooperative, solo, head-to-head)
- API endpoints:
- POST /api/player-stats/record-game - Record game results
- GET /api/player-stats - Fetch all user's players' stats
- GET /api/player-stats/[playerId] - Fetch specific player stats
- React hooks:
- useRecordGameResult() - Mutation hook with cache invalidation
- usePlayerStats() - Query hooks for fetching stats
- Game integration: Matching game now records stats on completion
- UI updates: /games page displays per-player stats in player cards
Stats tracked: games played, wins, losses, best time, accuracy,
per-game breakdowns (JSON), favorite game type, last played date.
Supports cooperative games via metadata.isTeamVictory flag where
all players share win/loss outcome.
Documentation added:
- GAME_STATS_COMPARISON.md - Cross-game analysis
- PER_PLAYER_STATS_ARCHITECTURE.md - System design

Major improvements to the games hero carousel:
- Added smooth autoplay (4s delay, stops on interaction/hover)
- Made carousel full-width to reduce virtual scrolling artifacts
- Added horizontal padding for better buffer on edges
- Restructured layout: carousel is now full-width, rest of content
remains constrained to max-width
- Removed containScroll setting to improve infinite loop behavior
The carousel now smoothly rotates through games automatically and
has better visual consistency at the loop edges.

Added overflowX: hidden to page container to clip carousel at viewport
level. This prevents the infinite carousel from making the entire page
horizontally scrollable while still allowing game cards to visually
extend beyond their container.

Removed non-functional wheel scrolling code and changed games carousel
to overflow: visible for a full-width effect that extends beyond the
container. Creates a more immersive, cinematic feel where game cards
bleed into the page edges.

Changed carousel wheel scrolling from discrete next/prev jumps to smooth
scrolling that follows the wheel delta. Now it feels like actually
scrolling instead of a rocket engine!
- Uses embla's internal scroll container directly
- Scales wheel delta by 0.5 for comfortable scroll speed
- Maintains horizontal scroll and shift+scroll detection

Both games and player carousels now support horizontal scrolling with:
- Mouse wheel horizontal scroll (trackpad swipe gestures)
- Shift + vertical scroll for horizontal navigation
- Prevents page scroll when interacting with carousel
Implemented with custom wheel event handlers that detect horizontal
scroll intent and call embla's scrollNext/scrollPrev methods.

Fixed carousel looping issue by replacing generic 'transition: all' with
specific transition properties. Only transition opacity on carousel items
and transform/box-shadow/border-color on cards for hover effects.
This prevents CSS transitions from interfering with embla's carousel
transform animations at the loop wrap point.

Added a hero section at the top of the games page featuring a rotating
carousel of all available arcade games. Each card shows:
- Game icon and name
- Difficulty and player count
- Description
- Category chips (Multiplayer, Memory, Soroban, etc.)
- Game-specific gradient background
Uses embla-carousel for smooth dragging and navigation dots with game
icons for quick access. Cards link directly to each game's arcade page.

Fixed AppNavBar auto-detecting /games route as needing minimal mode.

/guide), not the minimal arcade nav with only a hamburger menu.
Changed route detection to only apply minimal nav to /arcade/* routes,
not /games route.

The static icon.svg has been replaced by dynamic day-of-month favicon

Update favicon design based on user preference:
- Ones place: Gold (#fbbf24, stroke #f59e0b)
- Tens place: Purple (#a855f7, stroke #7e22ce)
- Remove background circle for clean, transparent appearance
The royal color scheme provides better contrast and a more
sophisticated look while maintaining excellent legibility at small sizes.

Use asymmetric padding to crop tighter to the active bead region:
- Top: 8px (some breathing room above)
- Bottom: 2px (minimal gap below last bead)
- Sides: 5px
This eliminates the visible gap of column post structure below the
last active bead while maintaining clean spacing above.

Previous approach used transforms to scale the entire SVG, which didn't
actually crop anything - just scaled everything uniformly.
New approach uses nested SVG with viewBox to truly crop the content:
- Outer SVG: 100x100 canvas with background circle
- Inner SVG: Uses viewBox to show only the cropped region
- viewBox dimensions vary per day based on active bead positions
Results:
- Day 1 (1 bead): viewBox height ~59px (narrow vertical crop)
- Day 15 (mixed): viewBox height ~88px (medium)
- Day 31 (many): viewBox height ~104px (tall vertical crop)
- Horizontal: Always ~110px (both columns with posts)
This actually maximizes bead size by showing only the relevant vertical region.

Clarify that horizontal and vertical cropping use different criteria:
- Horizontal (X): Always show full width of both columns (from structural rects)
- Vertical (Y): Crop dynamically to active bead positions + heights
This ensures consistent horizontal scale (0.8) across all days, with only
vertical positioning adjusting based on where active beads are located.

Refined the cropping algorithm to include structural elements (column posts)
in the bounding box calculation, not just active beads. This ensures the
complete abacus structure is visible.
Algorithm changes:
- X range: Full width from leftmost to rightmost post (all columns)
- Y range: From top active bead to bottom active bead (tight vertical crop)
Results:
- Consistent scale of 0.8 across all days (vs original 0.48)
- Shows complete column structure with posts
- Vertical position adjusts based on active bead positions
- Maintains visual context while maximizing bead visibility

Implement bounding box calculation to crop the favicon SVG to show only
the active beads, maximizing their size within the 100x100 icon canvas.
Algorithm:
1. Parse rendered SVG to find all active bead positions (via regex)
2. Calculate bounding box with 15px padding
3. Compute optimal scale to fit within 96x96 (leaving border room)
4. Apply transform: translate + scale + translate to crop and center
Results:
- Day 1-9 (few beads): scale ~1.14 (2.4x larger than before)
- Day 31 (many beads): scale ~0.74 (1.5x larger than before)
- Original fixed scale: 0.48
This uses no external dependencies - just regex parsing of the rendered
SVG to extract active bead coordinates.

Metadata fixes:
- Update icon path from /icon.svg to /icon to match route handler
- Ensure proper MIME type (image/svg+xml) is set in both metadata and response
Favicon visibility improvements:
- Increase AbacusReact scaleFactor from 1.0 to 1.8 for larger beads
- Add hideInactiveBeads prop to hide inactive beads
- Add hide-inactive-mode class to wrapper for CSS to take effect
- Adjust outer scale to 0.48 to fit larger abacus in 100x100 viewBox
- Reposition abacus with translate(28, -2) for proper centering
CSS cleanup:
- Strip !important declarations from generated SVG (production code policy)
- Apply same fix to OG image generator
User needs to restart dev server to clear in-memory cache.

- Create scripts/generateDayIcon.tsx for on-demand icon generation
- Route handler calls script via execSync (avoids Next.js react-dom/server restriction)
- Implement in-memory caching to minimize subprocess overhead
- Show current day (01-31) on 2-column abacus in US Central Time
- High-contrast design: blue/green beads, 2px strokes, gold border
- Document SSR pattern in .claude/CLAUDE.md for future reference
Fixes the Next.js limitation where route handlers cannot import react-dom/server
by using subprocess pattern - scripts CAN use react-dom/server, route handlers
call them via execSync and cache the results.

Replaced manual HTML/CSS abacus representation in opengraph-image.tsx
with server-side rendered AbacusReact component, using the same SVG
extraction approach as icon.svg and og-image.svg.
Now all three image generation methods use the actual AbacusReact
component from @soroban/abacus-react instead of manual recreations.
Changes:
- Added renderToStaticMarkup and AbacusReact imports
- Added extractSvgContent() function to parse SVG from rendered markup
- Replaced 150+ lines of manual HTML/CSS with AbacusReact render
- Embedded extracted SVG in ImageResponse via dangerouslySetInnerHTML
Benefits:
- Consistent abacus rendering across all images
- Automatic updates when AbacusReact component changes
- Significantly less code to maintain

Fixed generateAbacusIcons.tsx to properly extract SVG content from
AbacusReact server-side renders, removing invalid div wrappers that
prevented the abacus from displaying in icon.svg and og-image.svg.
Changes:
- Added extractSvgContent() function to parse rendered markup
- Regenerated icon.svg with proper SVG structure
- Regenerated og-image.svg showing abacus value 123
- Removed unused React import (modern TSX doesn't need it)
The Open Graph image now correctly displays the abacus visualization
alongside the site text, fixing the issue where only text was visible.

Fixed board rotation issues when guide is docked:
- Board now prioritizes HEIGHT when in portrait orientation
- Removed CSS constraints (maxWidth, maxHeight, aspectRatio) that were
interfering with explicit dimensions during rotation
- Board properly fills container whether guide is docked or not
- Smooth transition between portrait and landscape orientations
Technical changes:
- Set maxWidth/maxHeight to 'none' when svgDimensions are explicit
- Set aspectRatio to 'auto' when rotating to prevent override
- Cleaned up debug logging

Fixed hover error tooltip to properly check pyramid pieces by testing
all 4 pyramid faces for valid capture relations. Previously the code
was using getEffectiveValue() which returns null for pyramids, causing
the tooltip to never show.
Now for pyramid pieces, the code iterates through all 4 faces and only
shows the "No valid relation" error if NONE of the faces can form a
valid relation with the target piece.
