/* ============================================
   Section-level overrides
   --------------------------------------------
   Two per-section overrides applied via attributes on a
   [data-section-type] element. Editor UI (gear menu) persists
   these to localStorage with keys:

     aed:sec-theme:<pathname>:<typeKey>:<index>     → "light" | "dark" | "white" | "black" | "primary"
     aed:sec-parallax:<pathname>:<typeKey>:<index>  → "on"

   A small inline script in Base.astro applies them to the
   matching sections on load, so the override survives reload
   regardless of whether the editor is active.

   1. Theme override
      Re-declares theme tokens at the section scope so the
      entire subtree inherits a different palette than the page.
      Keeps accent/brand colors intact.

      **Scope to Vibrant mode only.** In Dark or Light mode the
      site is uniform — every section matches the root palette
      and per-section overrides are intentionally flattened. The
      overrides only come alive in Vibrant mode, where the hero
      anchors dark and the authored rhythm of white/primary/light
      sections breaks the page into contrasting bands.

   2. Parallax background
      Adds a full-bleed background image layer to the section
      via a pseudo-element, using background-attachment: fixed
      for a simple parallax effect. Image source is set via
      the --sec-parallax-url CSS variable the editor writes
      onto the element's style attribute. Parallax is independent
      of the three site modes — a section keeps its texture in
      all of them.
