/**
 * aurora.css — EMPTY, and kept for one release.
 *
 * ═══ THE OVERLAY IS FULLY PORTED (2026-09-07) ═════════════════════════════
 * The 2026-09 redesign arrived as a built artefact: a single-file build with
 * a 371 KB stylesheet and a 44 KB script appended to the end of `<body>`. It
 * shipped as this overlay so the approved look could go live the same day,
 * with every block marked as owing a port into the source. All of them have
 * now been ported, and this file holds nothing.
 *
 * Where each block went:
 *
 *   the aurora field        src/styles/aurora.css (".au-plate", ".au-layer")
 *   who renders it          src/components/brand/BrandPlate.tsx
 *   retiring the old        src/index.css, "THE ONE GROUND"
 *     per-section lights
 *   the closing band        src/pages/marketing/sections/EmberBanner.tsx
 *   type                    src/styles/fonts.css, index.css, tailwind.config
 *   glass buttons           src/index.css, "LIQUID-GLASS PRIMARY BUTTONS"
 *   the refraction filter   src/components/brand/AuroraGlassFilter.tsx
 *   the services carousel   src/pages/marketing/ServicesPage.tsx
 *   the About figures       src/pages/marketing/about/figures.tsx
 *   the convergence diagram src/pages/marketing/sections/why/partners.tsx
 *   the balance plot        src/pages/marketing/Agencies.tsx (AgingCard)
 *   the Why chat            src/pages/marketing/sections/why/WhyLoops.tsx
 *   counters and eyebrows   deleted at ~20 render sites; `Kicker` is gone
 *   the copy and type pass  src/index.css, "THE COPY AND TYPE PASS"
 *
 * ═══ WHY THE FILE IS STILL HERE ═══════════════════════════════════════════
 * `index.html` still loads it, and a deployed page that has been open in a
 * browser tab since before this release will ask for it on its next reload.
 * Serving an empty file is a 200; deleting it is a 404 in someone's console.
 * Delete this file AND its two tags in `index.html` together, next release.
