/* =====================================================================
   Origami Geometric — the site's one visual identity, scoped under
   body.origami-world. Every page on the site now carries this class;
   there is no remaining unstyled/bare baseline. See DESIGN.md.

   One shared page shell (max-width, margin, padding) on every page —
   nav and footer always sit flush within it, exactly like the home page.
   Two restrained-tier variants then cap their own inner content to a
   comfortable reading measure (craft-floor's 65–75ch guidance), the same
   way the home page caps its own hero/feature paragraph widths rather
   than letting text stretch the full shell:
   - .origami-world.origami-landing — full expression (home page, Persuade)
   - .origami-world.ask-page         — restrained (the ask page, Operate)
   - .origami-world.origami-page     — restrained (every other page)
   Shared rules below (nav, footer, workspace-tabs, beta mark) apply
   across all three; each variant section below adds what's specific.
