/* ============================================================
   Wisdom & Wonder — stylesheet
   Palette is drawn from the site's own subject matter:
     - sage paper   : calm, easy on ageing eyes, low glare
     - deep ink      : primary text, near-black but warm
     - marigold      : accent for actions & highlights
     - dusk indigo   : links, night-sky topics (space/astrology)
   Type: Lora (headings, literary) + Atkinson Hyperlegible
   (body) — Atkinson Hyperlegible was designed by the Braille
   Institute specifically to maximize legibility, which is why
   it is used here for every paragraph of reading content.
