/* art.astonhotelriga.com — public site.
   Design tokens from astonhotelriga.com (brief §6). Mobile-first: the primary
   device is a phone held next to a painting — designed at 360–430 px first.

   Typography rules (domain):
   - Headings: 'Forum' (single 400 weight). NEVER bold — no real bold exists
     and browsers would synthesize a mushy fake. Hierarchy via size only.
   - Forum keeps letter-spacing: normal — tracked Forum makes Latvian
     combining marks drift sideways (verify any change on /styleguide).
   - Forum is self-hosted below as ONE face with no unicode-range: the Google
     API's Forum subsets make Chromium compose ā/ē/ī/ū from base + combining
     macron (which Forum can't position) instead of its precomposed glyphs.
     Do not switch Forum back to the API link without re-passing /styleguide.
   - Body/UI: 'Montserrat' 400/500/700 (Google API — renders Latvian fine).
     Safe to track lightly. */
