/* Ophthalmic Academy, public website.
   Dark glass in blue, the same surface as the app's Dark theme. Headlines are set tall and
   condensed in Big Shoulders, like chart and instrument lettering; everything a buyer reads is
   Instrument Sans at a size it can be read at.

   Layout and type follow the October 2026 design audit (Public site and sign-in, items 04 to 10):
   one hero size (88/80, the only text that large), section heads a clear step down at 56/52, body
   copy at 16/26, 13px as the floor for basis lines, one filled button per hero, an 80px gap between
   sections (48px on a phone).

   Those are the sizes at 1920 wide and below. On a larger display the page scales continuously
   rather than in steps: the column widens with the window (--wrap), the display type, section gap
   and grid gaps grow with --k (1 up to 1920, 1.2 at 2560, at most 1.25), and running text grows
   far less with --kt (at most 1.08, so 16px body copy tops out near 17px) and keeps its measure in
   ch. Short laptop windows take their hero lead-in from the window height. */
