/*
 * Tiny Studio — Notion-inspired refinement (2026-04-06)
 *
 * Design reference: ./DESIGN.md (Notion aesthetic, from awesome-design-md)
 *
 * What changed from the prior AI-default styling:
 *   - Inter Variable from Google Fonts replaces Avenir Next as the primary
 *     sans, with Notion's negative-letter-spacing scale on display sizes.
 *   - Iowan Old Style serif retained ONLY for the brand mark (the "TS"
 *     square) and the literal hero h1 — no longer used everywhere.
 *   - Whisper borders (rgba(0,0,0,0.06)) replace medium borders.
 *   - Multi-layer shadow stack with sub-0.05 individual opacity replaces
 *     the single heavy drop shadow.
 *   - Backdrop-filter blur removed from light cream cards (Notion is opaque)
 *     and kept ONLY on the dark navy hero panel where it actually adds depth.
 *   - Four-weight typographic hierarchy: 400 / 500 / 600 / 700.
 *   - Warm near-black text via rgba(16,23,34,0.95).
 *   - Tighter vertical rhythm with explicit section spacing tokens.
 *   - Section alternation surface (.section--warm) for warm-white background
 *     rhythm between cream and tinted sections.
 *
 * What was kept (Tiny Studio's signature):
 *   - Warm cream background gradient with the radial-warmth corners.
 *   - Teal #0d8b78 as the singular brand accent.
 *   - Clay #c67a52 as the secondary warm accent.
 *   - Pill (999px) primary CTA buttons.
 *   - Generous (24-32px) radii on hero/feature cards.
 *   - Reveal-up entry animation and prefers-reduced-motion override.
