/* Tomosu AI, site-wide visual theme. Loaded LAST on every page, after site.css /
   site-nav.css / blogs/styles.css / responsive.css and any inline page styles.
   The system follows depthfirst.com: Inter only (headings weight 500, tight
   tracking), near-white page, near-black ink, grey secondary text, hairline
   borders, flat 8px cards, 6px-radius buttons, a quiet neutral nav.
   It works by (1) re-mapping the shared colour/font tokens every page already
   uses and (2) overriding the shared chrome (nav, footer, buttons). */
