/* ════════════════════════════════════════════════════════════════════════
 * bond-inbox-stack.css — desk-of-envelopes inbox (Phase G, 2026-05-22)
 *
 * The canonical Bond inbox is NOT a list of cards or a Gmail thread. It
 * is a desk: each sender has ONE envelope on the desk, with depth-shadow
 * stacking showing how many letters they've written. The wax seal IS the
 * identity (no avatars, no initials circles). Unread envelopes wear a
 * subtle amber wax-pulse. Long-press / right-click opens an action menu.
 *
 * Sent tab uses a four-state progressive paper-darkening status chain:
 * Sent (lightest cream) → Delivered → Opened → Savored (deepest cream).
 * Color transitions are CSS custom properties; no JS animation library.
 *
 * Pure CSS — no image assets, no external SVG filter files. All textures
 * are inline (gradients, repeating-linear-gradient, box-shadow stacks).
 * ════════════════════════════════════════════════════════════════════════ */
