/* ═══════════════════════════════════════════════════════════════════
   PROTEK ROOFING — Design A (Tracciato remapped to [data-design="a"])
   All selectors scoped to [data-design="a"] — zero [data-design="a"] left.
   Keyframes prefixed: a- (design-a namespace).
   Motion: transform / opacity / clip-path ONLY — no layout props animated.
   Hover transforms: inside @media (hover:hover) and (pointer:fine).
   No scale(0) starts — entrances from scale(0.95) or translateY.
   Principles: H-1/2/3 · HERO-1/2/3 · AMB-1 · INT-1 · PTR-1/2/3
