 * Snaplot — Mailroom (lot-by-photo)
 * ----------------------------------------------------------------------------
 * Mounts on [snaplot_mailroom]. Two phases on one page:
 *   Phase A — drop unsorted photos (reuses bulk-upload's drop-zone language)
 *   Phase B — drag photos from "Unassigned pool" into lot buckets, then
 *             Auto-bundle / Finalize → commit
 *
 * Visual conventions (shared with bulk-upload.css + catalogue-view.css):
 *   - Navy primary  #0E2A47
 *   - Amber accent  #F59E0B
 *   - Cream cards   #FAF6EC
 *   - Slate text    #334155
 * ========================================================================= */

/* Mailroom design tokens.
 * Defined on BOTH `.snap-mr` (the page shell) AND `.snap-mr__modal-overlay`
 * + `.snap-mr__toast` because those get appended to document.body and
 * therefore live OUTSIDE the .snap-mr cascade. Without the second
 * declaration, `var(--mr-navy)` resolves to nothing inside the modal —
 * which made the primary button (white text on transparent + white border)
 * effectively invisible. */
