 * Site-wide header polish.
 *
 * Applied on every non-single-gallery page: home, channel pages, tag
 * archives, discover, search, about, etc. Single video pages are excluded
 * server-side via is_singular('gallery') in render().
 *
 * Changes:
 *   - Backdrop blur so content scrolls past with a frosted-glass effect
 *   - Thin hairline border at the bottom
 *   - Vertically-centered nav/logo via flex (the original theme uses
 *     absolute-positioning inside block display, which breaks when extra
 *     items like a "Submit music video" button render)
 *   - Nav link hover goes neon-green
 *   - Gains opacity on scroll for legibility once hero is out of view
 *
 * On channel pages (body.tax-gallery-categories), the header is rendered on
 * top of the hero backdrop — no black bar — for an editorial, Netflix-style
 * effect.

   MENU CHROME — v4 (April 2026) hover-scale + dot box-shadow fix
   -----------------------------------------------------------------------------
   The Customizer's "Additional CSS" sets a 1.15× scale-up on top-level
   nav icon hover and a 1.4× scale on the dropdown indicator dot. Combined
   with the tooltip plugin's [data-alts-tip]::after rule (which has a
   liquid-glass box-shadow stack), the dot rendered as a giant green
   ellipse blob and the icon felt like it was launching into space.
   
   This block competes with the Customizer rule via higher specificity
   (extra `body:not(.single-gallery)` ancestor) and explicit !important
   to win cleanly. It restores the dot to a clean 4px circle with NO
   inherited box-shadow / filter / backdrop-filter, and tones the hover
   scale to 1.05 / 1.2 — visible but not aggressive.
   
   Belt-and-braces with altsounds-tooltips.js v4 which adds
   data-alts-tip-skip="1" to nav menu links so the tooltip system
   never claims them in the first place.
   ============================================================================= */
