- Multi-action system: each key supports multiple actions with different triggers
(tap, long_press, double_tap, hold_start, hold_end)
- GestureEngine: timing-based gesture detection with configurable thresholds
- New config types: KeyAction, TimingConfig, DisplayOutput
- Display output now supports JSON format (text/background/text_color) and
first-line-as-hex-color format for dynamic key backgrounds
- Display background colors are reflected in the web UI on the grid
- renderUnicodeText/renderUnicodeTextOnImage accept custom text color (fg)
- Global font setting (medium/regular) in Settings UI
- PageManager.defaultFont used as fallback for per-key font
- Alpine.js bundled locally (no CDN dependency)
- Web UI: action tabs (Tap/Long Press/Double Tap/Hold), unified More section
with appearance + display settings, gesture timing sliders in Settings
- Grid: subtle action type icons in top-left corner matching display indicator style
- Backward compatible: old config 'action' field auto-migrated to 'actions' array
- M+ 1m font files in assets/ for reference
- Updated config.example.json and README with all new features
