/* Theia website — v2 (2026-10-07), in the THEIA brand (theia-brand-guidelines.html v1.1).
   Layout: an engineering document on a 12-column, 1200-px measure. Dark cover bands (hero, page heads, the call to
   action, footer) carry registration marks like the company-profile cover; paper and mist sections sit between them.
   Section labels are tracked capitals over a hairline with a red index. Type is Inter at 400 / 500 / 600 only.
   Red is the measured point and nothing else: the crosshair, an index, a marked tooth, a full stop. */
