Regression aus v0.3.0: Die UI-Trefferprüfung (egui layer_id_at) wertete eine bildschirmfüllende egui-Ebene der Ordnung Background als UI. Dadurch galt jeder Punkt auf dem Blatt als Oberfläche, und Maus, Stift und Touch zeichneten nicht. Background-Ebenen zählen jetzt nicht mehr als UI; die Prüfung liegt in ui.rs und ist durch einen Test abgedeckt (Blattpunkte, Leiste, Skalierung 1 und 2). Außerdem: - 25 ungültige vormultiplizierte Farben (RGB > Alpha) auf unmultipliziert umgestellt: Knöpfe in Dialogen waren weiße Kästen mit unlesbarer Schrift, die Auswahlfüllung war deckend statt durchscheinend - Zeichen ohne Glyphe in den egui-Schriften ersetzt (✓ ✕ ● ↑ ↓, Variantenzeichen U+FE0F hinter ⚠) - Tests finden künftig ungültige Farben und nicht darstellbare Zeichen in ui.rs, selection.rs und main.rs Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
