/*
 * Teacher-App PWA — Brutalist Rock Edition
 *
 * Design rationale:
 *   - Pure black canvas, hochkontrastig — wie ein Album-Cover
 *   - Anton-Display für Headlines (kondensiert, kraftvoll)
 *   - JetBrains Mono UPPERCASE für Eyebrows (Album-Liner-Note-Vibe)
 *   - Inter für Body (modern, lesbar bei 15-16px)
 *   - Brand-Rot #e4003a sparsam, mit Glow für Aktivzustände
 *   - Reduzierter border-radius (max 8px), scharfe Kanten
 *   - Cards mit dünner Top-Border in Brand-Rot — Signature-Detail
 *   - Subtle SVG film-grain als Body-Background-Overlay
 *   - Schnelle Microinteractions (140ms), scale-on-active für tactile feel
