/* ===========================================================
   VectorScaleDB — Canonical navigation + footer (scoped)

   Bridge stylesheet for index.html ONLY.

   index.html renders its bespoke hero / value-card / terminal body
   from theme.css + the Tailwind CDN, NOT from style.css. The other
   84 pages get the canonical nav + footer styling from style.css.
   This file ports the NAV-ONLY (+ canonical footer) rules out of
   style.css so index.html can present the exact same injected nav
   markup (VsdbComponents.renderNav / renderFooter) without pulling
   in style.css, whose `.section` / `.card` / `.hero` / `.container`
   selectors collide with the names index's body relies on.

   Collision handling:
   - theme.css ALSO defines `.nav`, `.nav-links`, `.nav-hamburger`,
     `.mobile-menu`, `.mobile-menu a` (used only by the bespoke nav
     this file replaces). The canonical nav element carries
     `id="nav"` and the mobile menu carries `id="mobile-menu"`, so
     the colliding top-level rules below are anchored to those ids.
     Higher id-specificity wins over theme.css's bare class rules
     regardless of stylesheet load order — no body restyle, no
     dependence on this file from the other 84 pages.
   - The canonical color tokens (`--border`, `--text`, `--text-muted`,
     `--accent`, `--accent-purple`) live in style.css's `:root`, which
     index.html does NOT load. They are re-declared LOCALLY on the nav
     + footer roots below (resolved to their style.css values) so this
     file is self-contained and the tokens never leak to the body.
