   accentinformatics.com — shared stylesheet
   =========================================================================
   Brand colours are taken from the company logo: the salmon block (#F4525A)
   and white "greater-than" prompt glyph. The prompt is the organising idea —
   a computing company — so the accent colour and the eyebrow labels lean on
   that terminal feel without turning the whole site into a fake console.

   Fonts are the system UI stack: zero network requests, nothing to license,
   native rendering everywhere. The logo image carries the brand typography
   (Ubuntu + a script face), which is where it actually matters. If you later
   want a distinctive typeface, self-host a .woff2 in assets/fonts/ and swap
   --display / --body below — nothing else needs to change.

   Everything is driven by the custom properties in :root. Change a colour or
   a size there and it updates across every page.
