/* ==========================================================================
   Belleville Spray Foam Insulation - stylesheet
   Hand-written. Not generated by build.py (rerun build.py after editing so
   the ?v= fingerprint in every page updates).

   Design notes
   - Palette: Quinte olive (weight), ochre (action, the colour of a fresh
     lift of closed cell foam), limestone grey (alternate sections, the rock
     the city stands on). Every text/background pair below was computed with
     the WCAG relative-luminance formula; figures are in the comments.
   - Type: Archivo, one variable family. Headings run expanded (wdth 112)
     and heavy; body runs at normal width. Self-hosted in /fonts/.
   - Signature: the depth ruler down the seam of the home hero, with a foam
     line that rises once on load. Inner heroes carry a short tick strip on
     their lower edge so the device threads through the site. Everything else
     stays quiet: no shadows on cards, no labels above headings.
