/* =============================================================================
   OpenGoose.AI — marketing site design system  ·  "Ink & Paper"
   Self-hosted Google Sans Flex (Lato fallback). Monochrome by design, à la
   deepmind.google: white + cool-grey surfaces, near-black ink (#121317), and
   NO brand accent colour in the chrome. Colour appears only in the model
   logos. Ink + typography carry the page. Light theme only. No third-party
   CDN, no scroll-hijacking animation.

   Type scale — aligned to values measured on deepmind.google (2026-07,
   getComputedStyle; they use the very same Google Sans Flex):
     display 56px  w300  ls ≈0        lh 1.00   (the bigger, the LIGHTER)
     h2      32px  w500  ls -0.017em  lh 1.06
     h3/card 20px  w500  ls ≈0        lh 1.45
     body  17.5px  w400  ls +0.012em  lh 1.45   (slight POSITIVE tracking)
     nav   14.5px  w500  — pill hover
     button 14.5px w450  — full pill (r 9999), padding 8×16
   Nothing on their site is heavier than 500. We follow the same rule: large
   text gets lighter (350 for the hero), UI text tops out at 500, and body
   copy carries a hint of positive tracking. The variable font makes the
   in-between grades (350/450/550) render exactly.
