   ASSETNERVE — public marketing site (ESL focus)
   Shares the Vitrine product's "ink & paper" tokens so the site and
   the app read as one company, with a livelier marketing palette on
   top (per-sector tints, LED colours). Physical-device colours
   (plastic shell, e-paper film) are constant across themes — a white
   tag is white in dark mode too.
