Minimap: - Auto-shows in bottom-right corner when zoom > 1.05 - Renders full board content at scale (background + all strokes) - Purple viewport indicator with darkened outer areas - Click/drag to jump-pan the viewport - Cleaned up on destroy() Ruler/protractor property controls: - Rotation handle (purple ↺) — drag to rotate around origin - Resize handle (cyan ↔) — drag to change length/radius - Protractor now supports rotation via ctx.rotate(ov.angle) - Floating props panel in toolbar: angle° and length/radius inputs - Panel auto-shows on first click/drag, hides when overlay toggled off - Canvas-space hit testing with rotation-aware local coordinates Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-04-12 10:12:27 +03:00
