/* planalways.com — the public page.
   Tokens: primitives from docs/PLANALWAYS_DESIGN_SYSTEM.md §2.1, semantics from §2.2
   (light). Site-only deviations, deliberately: --pa-bg-sunk is §2's --pa-bg-surface-sunk;
   --pa-fg-on-inverse-2, --pa-fg-accent-on-inverse and --pa-shadow are not in §2; and dark
   mode keeps the header and hero navy instead of §2.3's warm/navy inversion, because
   navy-200 text on warm-100 would fail contrast. Fonts are the app's own self-hosted files (Instrument Serif, Manrope — both
   SIL Open Font License 1.1), so the public page and the app look like one product
   and no request leaves for a third-party font host. No JavaScript on this site. */
