feat(t5): Fokusring für alle, 44-px-Ziele bei Touch, 16-px-Schrift (T5a A5)
- globals.css: eine Basisregel :where(:focus-visible) mit --focus-width und --focus-offset (Sonne 3 px), Firefox-:-moz-focusring gleichgezogen; --text-xs 0.8125rem. - Fokus-Codemod (scripts/codemod-t5-focus.mjs): eigene Ringe und outline-none raus, sm:h-/sm:size- zu pointer-fine:, Label-Zeilen mit focus-ring-within; Skript-Fokus (Lücken-Liste, „Gespeichert“) bleibt. - Button/Input 44 px, kompakt nur mit Maus; Icon-Knöpfe mit unsichtbarer 44-px-Trefferfläche bei Touch, Nachbarn mit genug Abstand. - 16 px in Feldern, Labels, Auswahl, Leerzuständen, Listentiteln. - .holo-stage auf allen Beute-Bühnen, .stage-card holt den Seitenring. - Baukasten-Wächter (src/styles/baukasten-guard.spec.ts) mit den Regeln aus A3–A5, Ausnahmen mit Grund; Kalender-Auswahl als Inset-Ring.
