/*
  Telosphere Holdings: stylesheet.

  STYLE NOTES (from the "Telosphere Holdings" design)
  - Mood: classical and calm. Cream paper, deep forest green, one warm brown accent,
    gold only for the acorn emblem. Generous white space, large serif headings.
  - 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.
