BUG-01+02: Resize via Pointer-Events + rAF (kein renderGrid-per-Move)
BUG-01: Resize-Handle griff nicht Items hatten `draggable=true` (HTML5-DnD). Der Resize-Handle war Kind des Items, also fired der Browser `dragstart` am Parent, sobald die Maus überhaupt auf irgendeinem Kind war. `e.preventDefault()` im `startResize()` mousedown-Handler kam zu spät — HTML5-DnD hatte den Move-Drag bereits übernommen. BUG-02: Resize-Drag war zäh Pro mousemove rief der alte Code `renderGrid()` auf, das die komplette Cell- und Item-Struktur neu aufbaute. Bei 60 events/s × 100+ DOM-Ops pro Render entstand sichtbarer Jank. Fix: - HTML5-draggable komplett raus. - Eigene Pointer-Events (`pointerdown`/`pointermove`/`pointerup`) für Move (startItemPointer) und Resize (startResizePointer). - Resize-Handle: `pointer-events:auto` auf Handle, `pointer-events:none` auf `::before` (Dreieck-Deko), eigene Listener, `stopPropagation()` damit Item-Handler nicht mitfeuert. - `touch-action:none` auf Handle und Item-Body → Touch-Devices scrollen nicht versehentlich beim Drag. - Beide Aktionen nutzen requestAnimationFrame, und nur die CSS-Geometrie (grid-column/grid-row) wird aktualisiert — kein renderGrid() während Drag. Erst beim Drop / Resize-End kommt der volle re-render + save. - Resize nutzt `setPointerCapture` damit der Move auch dann weiterläuft, wenn die Maus den Handle kurz verlässt. Beweis: tests/test_pointer_events.js (Node-basiert, ohne Browser) 1. Resize stopPropagation wird aufgerufen 2. Item-Body pointerdown erreicht nur Item-Handler (nicht Resize) 3. CSS pointer-events korrekt gesetzt 4. renderGrid() in keiner onMove-Funktion (0/2) 5. requestAnimationFrame wird genutzt (3 calls) 6. draggable=true komplett entfernt (0 assignments) 7. touch-action:none auf Resize-Handle ALLE 7 grün. Manuelle Verifikation gegen laufenden Server (?demo=1): GET /?demo=1 → 200, 91685 bytes grep draggable=true: 0 grep startItemPointer|startResizePointer: 6 grep pointerdown: 3 grep requestAnimationFrame: 3 grep HTML5-drag handlers: 0 (nur 1 in Kommentar) grep renderGrid(): 12, davon 0 in onMove-Handlern Closes #3 #4
