   ARK ROBUST TYPE TOKENS v2 (2026-10-20) - SHARED BLOCK. BEGIN.
   One block, reusable by every ARK Graystone site (arksauna.com, arksaunas.com store, ...).
   Nathan's robust-type standard: no thin or italic text, body 500, emphasis 600, labels 700,
   body 17 px+ on phones with 1.6 line height, body text 7:1 or better on Graystone,
   60 to 70 characters per line, gold only for short bold labels. See _build-landing/TYPOGRAPHY-NOTES.md.
   Fonts are resolved relative to this stylesheet: put it at /assets/x.css and the fonts at /assets/fonts/.
