/* casselberryhvac.com — "Workshop Estimating Desk"
   Iron, brass, paper. Restyled from the Stitch "Atelier & Spec" design
   import (design-import/atelier_spec/DESIGN.md) — colors, type scale,
   spacing and component shapes only; no copy, facts or numbers were carried
   out of that mockup. This file is the single source of the visual layer;
   build.py only ever emits the class names below.

   Rules of this system, so later edits do not soften it:
   - Absolute squareness. Zero border-radius anywhere, no exceptions.
   - Zero shadows, zero gradients, zero blur. Depth comes from a bounded
     rectangle and a rule weight, never from elevation.
   - Two rule weights only: a 1px hairline (--line-2, iron-rule) for
     ordinary dividers, and a 2px heavy rule (--line, tempered iron) for
     master boundaries — header, footer, section spines, framed panels.
     A 1px brass rule (--brass) marks an active, focused or trade-verified
     boundary. Nothing else.
   - Domine (structural slab serif) carries every heading and every large
     numeric readout. IBM Plex Sans carries body copy and every label —
     labels get their "technical" character from uppercase + letterspacing,
     not from a monospace face; DESIGN.md never specifies one.
   - Numbers are tabular everywhere. The site is an argument made of
     figures, sourced under every one of them.
