/*
  Telosphere Holdings: stylesheet.

  STYLE NOTES (from the "Telosphere Holdings" design)
  - Mood: classical and calm. Cream paper, deep forest green (#0A2C06) and METALLIC gold as the
    dominant accent. The metal effect is a blend of four gold tokens (shadow, base, light,
    shine) used on buttons, rules, the quote, the acorn and the sphere. Small text on cream
    uses --accent, a deeper flat gold, so it stays readable. Generous white space, large
    serif headings. Colors updated 2026-11-04 at Brindie's request.
  - Fonts: Cormorant Garamond (headings, Google Fonts), Work Sans (body and labels).
    Noto Serif is a fallback because Cormorant has no Greek letters.

  RULE: colors are set ONLY in the :root blocks below. Never write a hex color anywhere else.
  Keep --ui a sans-serif even though --display is a serif.
