/* ==========================================================================
   GEORGES RENOVATION — "Chantier alpin" theme (v3)
   Deliberately NOT the cream-paper + terracotta + condensed-signage cluster.
   Direction: an alpine renovation dossier. Deep spruce green is the brand
   surface (renew / forest), warm birch paper carries the light sections,
   and a single sawdust-ochre accent does the pointing. Display face is
   Space Grotesk (quirky neo-grotesk, wide-ish), body is Inter, and labels
   run in Space Mono like entries in a site logbook. Signature device: a
   left "index rail" with a section register (§01 …) instead of decorative
   numbering, and a fine ochre hairline that recurs as a seam.
