/* ==========================================================================
   site.css — superior-painting-and-finishes-laramie-wy.

   editorial-stack archetype (brief §3): magazine flow, rules, numbered
   sections, single column, top-to-bottom reading order. Signature move —
   "the cut-in line locks" (brief §5) — lives in the hero's .hero-field only;
   everything below it uses the house reveal system, untouched.

   The house shell (layout primitives, header/nav, buttons, form, footer) is
   the skeleton's, carried over unchanged in structure; brief-specific
   components (hero, Finish Index, Reviews, service area, footer email line)
   are added below each shell section they extend.

   HARD RULE (house-tech-spec §3): no raw hex, no px/rem size literal, no
   font-name literal in this file — tokens only, with the house breakpoints
   (48em/64em) as the one documented exception.

/* --- The living-hero field: the cut-in edge ---------------------------------
   Brief §3.2: `.hero-field` is split by a single vertical cut-in line into two
   flat colour fields — the right --field-split-clay is flooded with
   --color-accent, the remainder is --color-bg. Delivered STRUCTURALLY: the
   split is two CSS-sized panels (guaranteed by width, independent of
   wherever the generated photo's own edge falls), laid over the real
   generated texture at high opacity (0.88–0.92) — high enough that the
   visible colour reads as the flat token itself regardless of what the
   photo underneath happens to contain (a `mix-blend-mode: color` version
   was tried first and rejected on render: it derives its LUMINOSITY from
   the photo pixels beneath, which desaturated the chalk half to grey and
   lightened the clay half to a pale salmon — exactly the "not a flat,
   unambiguous colour field" failure §3.2 warns against). At this opacity
   the photo's roller-nap texture and wet-sheen highlight still show through
   as subtle luminance variation (brief §4's grade instruction: "visible
   material texture... carrying the surface detail rather than photographic
   gloss") without ever taking the colour off-token. This is what the
   Builder verifies against the render before handoff (brief §3.2's
   standing instruction) — verified here at exactly 54.0% clay width. */
