/* Altius Charter landing page (/charter/).
   Ported from Claude Design project "Altius Charter", file "Charter Page v4.dc.html".
   v4 is drawn at web scale (16-18px body, 20-21px titles, 11-12px mono labels),
   so sizes follow the design directly. The design's per-section "Altius Charter"
   wordmark is kept only in the hero. Sections are full-screen like the design
   (min-height 100svh, content centred, 40px vertical padding), dropped at <=991px. Tokens and .ds-btn come from assets/product/product.css. */
