/* ── WATERMARK (test — drop this block + its markup in layout/footer.html
   and scripts/footer.js if it doesn't work out) ────
   Oversized background wordmark pinned flush to the footer's bottom edge,
   edge-to-edge — deliberately ignores the content-inset/container-max the
   rest of the footer respects. Font-size alone can't guarantee an exact
   full-width fill (the word's natural width varies with viewport in a way
   a fixed clamp() can't track 1:1), so scripts/footer.js measures the
   text's natural width and stretches it to the footer's exact width via
   transform:scaleX() — left edge stays pinned (transform-origin:left),
   so it always spans precisely edge-to-edge with zero drift. */
