/* ============================================================================
   Sprig Edit tester-recruiting microsite — brand theme.

   GPR ships a neutral, tokenized base (Design Brief §9, D-22). Each recruiting
   microsite is a *theme* over that base: its own palette, type, and voice. This
   file is Sprig Edit's — a fresh blank page with one green sprig on it: crisp,
   minimal, ink-on-white, monospace accents for the markdown motif. Deliberately
   sparer than Pigeonpile's papery warmth or Away Team's travel brights, because
   the app itself manages exactly one document. Swapping this stylesheet re-skins
   the whole funnel without touching the signup logic. No external fonts or
   assets are loaded (CSP-safe, fast on Pages).
