/* Chris Ward Plumbing and Heating — demo stylesheet (Wave 4, V0.4).
   Art direction: "enamel trade-sign register". The page is built as a run of
   hand-painted British trade signage: a warm enamel cream field, deep bottle
   green enamel panels, oxblood only where a call action lives, and muted brass
   hairlines acting as the sign-painter's rules. Identity leads as oversized
   painted lettering next to one enamel sign plate carrying an original abstract
   maker's mark (a gauge arc, tile joints, a cropped ring, right-angle linework).
   The four supported service labels are set as full-bleed register bands whose
   type scale and field colour change band to band, so the set reads as a sign
   register rather than a card grid or a service catalogue.
   Palette: enamel cream, bottle green, near-black, oxblood red, brass. */
