   ANTSFACTORY — SITE
   Component styles. Reads tokens.css and never hard-codes a
   colour, font, radius or duration.

   House rules, from the design language:
   · display type is serif at weight 400 and never bolder
   · no drop shadows anywhere — elevation is a colour step
   · chromatic colour appears only on full-bleed tiles
   · body copy sits at --ink-dim, headings at --ink-85

/* ---------- The ground -------------------------------------
   A photographic nest section behind the whole page: real soil,
   with the galleries cut out of it rather than drawn on top.

   Three layers do the work:
     .ground       the earth — a graded soil photograph, cross-faded
                   against itself so it repeats with no seam
     .ground__ants three residents, positioned on the gallery centrelines
     .ground__cut  the same photograph, darker and softened, masked to
                   the tunnel network — so the void has real texture
                   inside it instead of being a flat shape
     .ground__lit  the wrapper, carrying a pale drop-shadow cast UPWARD
                   (light from the surface catching the top of each
                   gallery) and a black one downward (depth below)

   It starts invisible so the hero photograph owns the first screen.
   `max()` keeps the galleries at a believable scale on phones rather
   than shrinking the whole nest into a mesh. */
