/* ============================================================================
   Sherpa marketing site — shared design tokens (V2: green / charcoal)
   ----------------------------------------------------------------------------
   Single source of truth for the public site palette. Each page links this
   BEFORE its inline <style>; pages reference tokens via var(--…) only — they no
   longer carry their own :root block.

   Values mirror the app design system (lib/design-system/tokens.ts, ships in
   evident-ma-frontend #223/#224). The teal-on-white ban is structural:
     • peak   #19FADA — electric teal, FILL/STROKE ON CHARCOAL ONLY, never text.
                        Introduced surgically on dark surfaces in later batches,
                        deliberately NOT a base token here.
     • ink    #0B6B5E — the ONLY brand teal allowed as TEXT / thin mark on light.

   Token NAMES are kept from V1 (--navy, --blue, …) so the ~258 existing var()
   call-sites flip centrally without renaming. Names are now historical; the
   VALUES are V2. Font swap (DM Sans → IBM Plex Sans) is a separate batch.

   SITE HEADER — shared, one source of truth. The SAME full <nav> (logo lockup +
   PLATFORM / WHO IT'S FOR / PRICING / INVESTORS / CONTACT + teal GET STARTED) is
   used on home + pricing + investors + investors/capital — links are absolute so
   the identical markup works from any page. The investor funnel pages (nda /
   request-access / thank-you) intentionally keep a minimal .brand-header (logo +
   breadcrumb) to stay focused. Nav CSS lived inline in index.html; centralized
   here so the nav can't drift from the logo again.
