/* LongTable marketing — design tokens, reset, self-hosted fonts, base typography.

   External CSS only (no inline styles/`<style>` anywhere) so the CloudFront CSP
   (`script-src 'self'; style-src 'self'`) holds and the Mozilla Observatory grade
   stays high. See AGENTS.md.

   Palette — "Hearth", the theme LongTable adopted on 2026-09-04 (LongTable-app/bonfire
   #5247, #5250) and shares with the app: Teal for actions, links and focus; deep Teal
   for button rest and the dark bands; one Coral highlight (the logo's full stop, small
   accents); a Bone ground with Linen washes; Deep Teal headings; the Walnut wordmark.
   Every text/background pairing below is AA (>=4.5:1); the accent *text* token is a
   lighter step than the accent *fill* so links read as links while clearing AA on bone. */

/* ---- Self-hosted variable fonts (font-src 'self') ----
   Latin subsets, cut to the weights the site sets (400-700) with fontTools'
   instancer (`fonttools varLib.instancer <font> wght=400:700`); the serif keeps
   its optical-size axis for the display sizes. */
