/* ─── Clean-preview mode (Config → Pixels Phase 0 contract) ──────────────
 *
 * Activated by adding the `bg-clean-preview` class to `<body>`. Hides
 * everything that is UI chrome — handles, toolbars, drop indicators,
 * hover/focus rings, empty-cell placeholder glyphs — while preserving
 * everything that is content (rendered text, images, logo, cell
 * backgrounds, grid geometry). The bench harness forces this on before
 * screenshotting the DOM-editor authority so its output is comparable
 * against server-rendered authorities (Playwright, libvips/Pango, Pillow).
 *
 * Spec: memory/project_config_to_pixels_pipeline.md → Commitment 4.
 * Also hides elements explicitly tagged [data-ui-only="true"] — future-
 * facing hook for new chrome added after this toggle ships.
