/* ── sites/_shared/css/base.css — greenswans.eu and kencie.nl ────────────────
   The GreenSwans.AI "Greenhouse" palette and faces (CLAUDE-brand-greenswans.md),
   with the same one-job-per-colour roles: Ink text, Paper background, Forest
   action (button fill, links), Lake selection and hover, Sky info panels, Mint
   the action on Sky, Leaf accents on Ink only, Slate the quiet voice on Paper,
   Chestnut the wood (frames). No hex outside :root.

   Type: Libre Baskerville for headings and reading text, Instrument Sans for
   everything else, Fraunces for the "Green Swans" wordmark only. Self-hosted —
   never Google Fonts. Each site adds its own site.css on top of this file.
