/* ═══════════════════════════════════════════════════════════════
   Notes — pen on paper.

   Design language: a warm, subtly-textured sheet of paper; every
   piece of text is "ink" in one of six pen colors; chrome is kept
   to hairlines and handwriting. Mobile-first throughout — desktop
   just gets more margin.

   Theming: custom properties on :root are the light (paper) theme;
   html[data-theme="dark"] swaps to slate paper with chalk-bright
   inks. JS resolves the user preference (auto follows the system).
   html[data-style] picks the app style (paper | pro | typewriter) —
   see the "App styles" token blocks below and notes/DEVELOPMENT.md.
