/* TruFrame theme — the single source of colour for every prototype page.
   Dark is the default; light is opt-in via <html data-theme="light">.

   ROLE TOKENS come first and are what new code should use. The legacy
   stone/ink/water/rust names below are ALIASES kept so existing CSS keeps
   working; they are not a second palette.

   THE ONE RULE THAT MATTERS: colour carries meaning here.
     white  = the printed drawing sheet, and nothing else
     blue   = interactive, or produced by the draftsman
     red    = measurement — a dimension, an encroachment, an overshoot
   If something is red and is not a number that matters, it is wrong.
   The on-screen viewing board is --board, not --sheet. Glare-white is
   what prints; the working surface is charcoal (dark) or warm off-white
   (light) so a long session is not a lamp in the face (Craig, 2026-09-12).

   WARNING for anyone editing: --ink used to mean BOTH "text colour" and
   "a dark surface". Those are now --text and --surface-deep and they move in
   opposite directions between themes. Do not reintroduce a token that means
   both. */
