/* ============================================================
   Studio Practice — Design System v2
   Shared across all pages. Loaded via:
     <link rel="stylesheet" href="/assets/sp-design-v2.css">

   Apple-DNA premium direction. Off-white system, borderless,
   generous whitespace, real work as rest beats, modern motion.
   Techniques: OKLCH + color-mix, View Transitions, container
   queries, backdrop-filter (-webkit- prefixed), dvh, magnetic
   interactions, accessible reduced-motion paths, font-variation
   axes (Fraunces opsz + SOFT).

   Cascade layers (low → high specificity):
     reset       — normalizations
     tokens      — :root custom properties
     base        — typography, body defaults
     components  — nav, footer, carousel, cards, form, etc.
     utilities   — single-purpose helpers (.inner, .eyebrow, .reveal)
     overrides   — page-specific escape hatches
