   Served from our own origin — the CSP sets font-src 'self', and a
   font CDN would be blocked. /assets/* is cached immutably for a
   year, so these are downloaded once.

   Sora carries the display sizes: a geometric sans drawn for
   technical interfaces. Even stroke weight, open counters, tall
   x-height.

   It replaced Bodoni Moda, which was the readability complaint.
   Bodoni is a Didone — hairline thins by design, gorgeous on a
   banknote at poster size, and genuinely hard to read at heading
   size on a dark ground. The thin strokes were disappearing. That
   was the typeface fighting the medium, not a matter of taste.

   Manrope carries the body: drawn for screen reading, wide apertures,
   noticeably more legible at 16px than the Archivo it replaced.

   IBM Plex Mono sets every struck label and eyebrow.

/* Inline links in running prose. The negative margin keeps the line box exactly

   The padding is load-bearing and font-dependent. An inline box is sized by the
   font's em box, NOT by line-height, so switching body faces changes the height
   even though nothing here changed: at 0.75rem this measured 45px under the old
   fallback serif and silently dropped to 41px under Archivo.

   Under Manrope the em box is 21.9px at 16px (asc 2132 + desc 600 over 2000 upm),
   so 0.95rem padding gives 52.3px. Comfortable. If the body face changes again,
