/* Shared three-site house style (CLA-193, HUISSTIJL-DRIE-SITES.md, 28-09).
   This is the specimen's house.css (website-tasks/house-style-20260928) with one change:
   the font block. Literata and Inter are self-hosted from @fontsource-variable 5.3.0
   (OFL-1.1, "standard" files with the opsz and wght axes), latin + latin-ext subsets,
   the same approach as the ClarityOne house branch. Instrument Serif stays self-hosted.
   No request leaves for a third-party font service.
   Ben 28-09: the light ground is warm honey sunlight (--ivory #F3E2BE, --paper #F9EED6,
   --rule #E3CB9A; was #F4EAD8 / #FBF6EC / #D8C9AE), and the Afterglow skin uses these shared
   tokens instead of its own ivory. The night band is unchanged. */
