 * 2026-09-02 · home opener · measured, not assumed:
 *   34 no horizontal scroll — scrollWidth == clientWidth at 320/375/414/768/1280/1440
 *   49 contents rows stay one line at all six widths; row pitch 54.6px (> 44px tap)
 *   40 ink/paper 17.7:1 · ink/paper-3 15.0:1 · muted/paper 7.1:1 · muted/paper-3 6.1:1
 *      focus/paper 6.5:1 · focus/paper-3 5.5:1 — every pair clears its threshold
 *   54 the 目錄 kicker labels the list directly beneath it in its own column; it is
 *      not an eyebrow for the h1, which is a sibling in the other column
 *   45 the leaders are motivated — they carry the eye from a section name to its
 *      count, which is the contents-page device, not an ornament
 *   28 the first 好物 card is now the page's first image and lands at y=749 in an
 *      800px fold, so it takes fetchpriority="high" instead of loading lazily
 *
 * 2026-09-02 · paper stock · measured, not assumed:
 *   40/41 the tile was rasterised to a canvas and its alpha read back — mean
 *      0.017, peak 0.114. Every text/background pair was then recomputed with
 *      the ink speckle composited at the tile's DARKEST pixel, not its mean:
 *      ink/paper 13.96 · ink-2/paper 8.88 · muted/paper 5.62 · muted/paper-2
 *      5.24 · muted/paper-3 4.80 · accent/paper 5.06 · accent-deep/paper 6.61 ·
 *      focus/paper 5.13 · focus/paper-3 4.38 — every pair clears its threshold.
 *      muted-on-paper-3 is the binding pair and sets the peak alpha ceiling.
 *   29 not an abstract background: no accent, no gradient, no animation, no
 *      mesh. Grain is anti-patterns.md's own prescribed fix for the aurora
 *      blob, and the layer runs at ~0.017 against its < 0.1 ceiling.
 *   45 not hero decoration: the stock is uniform across all 25 pages and never
 *      enters the opener, so design.md's no-hero-enrichment rule still holds.
 *   34 no horizontal scroll at 320/375/414/768/1280/1440/1920 on all six page
 *      types (home, product, brand, archive-route, article, 404)

/* ─── the stock ────────────────────────────────────────────────────────────
 * One sheet, one tooth. --texture-paper is a transparent ink speckle, so a
 * surface sets its own background-COLOR and inherits the grain from here.
 * That is why no paper tint anywhere in this file uses the `background`
 * shorthand: the shorthand resets background-image to none, which would punch
 * a flat rectangle out of the page the moment a row was hovered.
 *
 * The line: the sheet and its tints carry the tooth — the page, the plinth
 * frame, the footer band, the menu sheet, the dialog panel, and every hairline
 * row that retints on hover. Controls (.chip), form fields (.search-input) and
 * image wells (.story-row__thumb, .story__figure) do not; they are a different
 * material laid on the sheet, and an asset covers them anyway.
 *
 * The masthead is not listed because it is transparent: it is the same paper
 * as the page, so it shows the canvas tooth by not painting over it.
 *
 * No background-attachment: fixed. Each surface starts its own tile, but at
 * mean alpha 0.017 with 38% of the tile fully clear the seam is below the
 * threshold of vision — and fixed attachment janks on iOS for no gain. */
