/* photoshrink.net — design system
   "Squeeze" identity: warm eggshell canvas, electric coral/yellow accent duo,
   big rounded tactile cards. System fonts only — zero external requests.
   Headline face leans on a rounder system sans (Avenir Next / -apple-system)
   set heavy and tight; a tabular monospace face carries every byte-size
   readout, so the "before/after" numbers feel like a real gauge. */
