/* Images tab — the Pictures / Art / Comics split chooser (renderer/media/images.js).
 *
 * A triptych over the whole Images view: a warm amber darkroom (real
 * photos), a cool violet atelier (drawn / rendered art) and a pink-neon
 * reading nook (comics), joined by glowing seams that carry the Hearth mark. Entering the tab
 * draws the seam top to bottom, then both halves unfold outward from it.
 * Hovering a half widens it, fans out three of its own thumbnails and wakes
 * its icon; picking one sweeps it across the view and hands over to the grid.
