/* =============================================================================
   NAVBAR  v18 — theme-aware, cinematic, premium
   -----------------------------------------------------------------------------
   Architecture
     • Bar is fully transparent by default — no background, no border, no shadow.
     • Each <section> declares its palette via  data-nav-theme="light" | "dark".
       The default (no attribute) is dark.
     • main.js observes sections with IntersectionObserver and mirrors the
       active section's theme onto  <header data-theme="...">.
     • CSS animates color, logo-filter and a subtle glass backdrop between
       the two states. No flicker, no layout shift, no transform tricks.

   States
     [data-theme="dark"]   — sits over a dark section (default).
                             Light text, inverted (white) logo, no background.
     [data-theme="light"]  — sits over a light section (cream #ede8df etc.).
                             Ink (dark) text, regular logo, soft translucent
                             dark glass background for legibility at speed.

   Dependencies (tokens.css):
     --ink, --ink-deep, --warm-white, --bronze, --bronze-pale, --bronze-light,
     --content-max, --page-gutter, --nav-height, --font-sc, --font-display,
     --ease-out
