/* ==========================================================================
   The Workshop HQ - typeface and palette chooser. DRAFT BUILDS ONLY.
   --------------------------------------------------------------------------
   Review scaffolding, exactly like the ig-* stand-in photographs. Three
   mechanical gates keep it out of a live build - see assets/js/theme-demo.js.

   The site is one of THREE typefaces and one of TWO palettes. There is no
   "current" option and no fallback theme: styles.css itself now ships
   option 1 (Fann Street) on palette A (Workshop), so this file carries only
   the DIFFERENCES for the other two typefaces and the other palette.

   That is why there is no [data-theme-type="fann-street"] block and no
   [data-theme-palette="workshop"] block. Selecting either simply matches
   nothing here, and the base stylesheet applies. Do not add empty blocks
   for them - the absence is the mechanism.

   Load order: this file comes AFTER styles.css and availability.css, so its
   overrides win at equal specificity.

   Every palette here is verified with `node scripts/check-contrast.mjs` and
   passes every gated pair. Do not hand-edit a hex without re-running it.

   1. Palette B - Oak, oxblood and aged brass

   A deeper reading of the same four materials the palette was sampled from -
   oiled oak, dark painted timber, oxblood brick, aged brass - as one warm hue
   family on a single lightness ladder. Still understated, still not a dark
   theme.

   Known risk, and it is not a token problem: a deeper, redder ground subtracts
   more warmth from every image it carries, so any cool-cast photograph reads
   distinctly bluer against it. Commissioned photography would need grading to
   suit this palette.

   on top of the design, never as part of the design being judged. Its own
