/* Alfaopus — shared stylesheet.
   Dark navy ground, ivory text, brass accent. Bodoni Moda for display,
   IBM Plex Sans for prose, IBM Plex Mono for the register/label voice.

   Fonts are SELF-HOSTED, not loaded from the Google Fonts CDN. That keeps the
   `default-src 'none'` CSP intact and keeps the privacy statement true: no
   request on this site reaches a third party. They are subset to Latin +
   Latin-1 + the punctuation used here, and instanced to weight 400 (Bodoni and
   Plex Sans are used at one weight only), which takes them from 224KB to 54KB.
   Bodoni keeps its optical-size axis so it adapts between the 20px thesis and
   the 46px wordmark. */
