/* ═══ MythLab — Shared Shell Stylesheet ═══════════════════════════════
   Used by terms.html, privacy.html, support.html.
   Mirrors the landing.html design tokens so the trail-pages feel like
   the same product. Lighter than the landing — no particle canvas,
   no constellation, no rotating frame. Just typography, surface,
   buttons, nav, footer.
