/* — Imagery treatment system ("Liner Notes") ————————————————————————— *
 *
 *  Full color is the DEFAULT. Real faces carry the humanity, so good images
 *  stay untouched. The salvage treatment is OPT-IN, for genuinely low-res
 *  assets only — never apply a global tint to all images.
 *
 *  HOW TO USE
 *  ----------
 *  Good image (default — full color, just a frame/aspect helper):
 *    <figure class="media media--full">
 *      <img src="..." alt="...">
 *      <figcaption class="caption">Artist — Song, 2019</figcaption>
 *    </figure>
 *
 *  Low-quality image to rescue (dusk-violet duotone + film grain at rest,
 *  BLOOMS to full color on hover/focus; caption framed like a liner note):
 *    <figure class="media media--salvage">
 *      <img src="grainy-old-photo.jpg" alt="...">
 *      <figcaption class="caption">Salvaged still, c. 2010</figcaption>
 *    </figure>
 *
 *  --salvage-shadow / --salvage-light / --grain-opacity are tokens; the grain
 *  is an inline data-URI SVG (fractal noise), so no extra asset request.
