/* ==========================================================================
   Agentic Worklabs · v6 · Bone + Grid
   --------------------------------------------------------------------------
   Design notes for the developer:
   - Paper: LinkedIn Cream (#F4F2EE), one notch lighter than the previous Pale Bone.
   - Surface: 40px blueprint grid dots, masked top-and-bottom. Visible on
     both light and dark.
   - Type: Geist sans + Geist Mono + Instrument Serif italic for punchlines.
   - Logo: bumped to 32px mark + 18px wordmark (the cherokee third slab
     should be legible at nav size).
   - Cherokee discipline: ONE cherokee moment per screen-fold. The logo's
     third slab counts as persistent chrome and does NOT count toward the
     per-screen budget. Italic-serif on words of consequence
     (enforcement, free) is cherokee. Other italic-serif moments are ink.
   - Cantilever-as-architecture: 4-slab proportional rhythm appears as
     the left-gutter ruler (.cantilever-ruler), the EU-block horizontal
     divider (.cantilever-divider), and the hero footer-rail
     (.hero-rail with 3·4·3·2 column spans).
   - No em-dashes anywhere in copy. Periods or commas instead.
