/**
 * CI-series — Common items management (Fase 15).
 *
 *   CI-01 Ana boosts "milk" → in /lists/<id> the dropdown shows it first
 *         even though seeded use_counts put other items higher.
 *   CI-02 Ana adds "pan" to the active list → the dropdown stops including
 *         it on the next keystroke.
 *   CI-03 Borja (member) opens /collective/manage → he sees the table but
 *         the action buttons are disabled.
 *   CI-04 Ana purges a row → the row disappears from the table and the
 *         dropdown stops showing it.
 *
 * Note: CI-02 lives in this file but exercises the /lists/[id] page, not
 * /collective/manage — it pairs with the exclude-on-list wiring landing
 * in the next commit (15.4). It is listed here because it is part of the
 * Fase-15 contract.
