   Visual Edition — design tokens and shared component styles
   lib/theme.css  (foundations; components never edit it)

   Identity: a precision instrument set in a book face. Warm
   paper ground, engraved hairlines, light serif readout numerals, and only
   three chromas: cobalt (mode A), signal orange (mode B), gilt (the kept
   fraction c). Theory is ink, always dashed; measurement is solid ink.

   Fonts are self-hosted OFL files in ../fonts/ (licences in fonts/LICENSES.md).
   No Google Fonts link is needed; this file declares every @font-face.
