/* ============================================================
   recursive-gift.css — shared stylesheet for all phyllotaxis.life pages

   Architecture:
   - Tokens (colors, type, rules) live in :root and are OVERRIDDEN by
     theme files (theme-default.css / theme-substrate.css / theme-mist.css /
     theme-bio.css). Anything register-specific belongs in those files.
   - This stylesheet is theme-agnostic. Every color reference uses a
     var(--token).
   - Plate fade colors and hairline accents are themed via dedicated
     plate-specific tokens so registers can shift them independently of
     core ink/paper.

   2. Cooperative — written with AI in the room. Signaled by a small
      "with Haru" attribution in the byline meta. No chrome.
   3. AI-led / guest — Haru (or another AI) is the primary author.
      Treated like a guest column in a magazine: inset framing,
      sister serif (Newsreader), inverted byline.

   Marginalia (the gutter notes) is orthogonal to all three modes.
