   PlanOS — Editorial Atelier theme
   Shared stylesheet for the marketing site (www.getplanos.com).

   One file of truth, ported from pro/mocks/shared.css and pro/src/index.css.
   Each marketing page links this and keeps only page-specific overrides
   in its own <style> block. Palette = "Linen & Ink" — near-white linen
   paper + true-black ink, with Clay as the signature accent. The higher
   paper/card contrast makes feature tiles read as cards, not washes.

   Palette: Ink / Paper / Clay / Sage / Gold — Clay is the signature
   accent, used sparingly on primary CTAs and key highlights.
   Type: Fraunces (serif display) + Inter (sans everything else).
