/**
 * User stories covered: Feature 12 — Cheapest & Closest tags
 *   - TECHNICAL user on /catalogue/items sees Cheapest or Closest tags on item rows
 *     when a site is selected (tags are independent of sort order)
 *
 * Feature 13 — Auto-sort by distance when site selected
 *   - Selecting a site from the site selector causes items to re-sort (URL param changes)
 *   - Default sort (no site) is by Price; after site selection it switches to Distance
 *
 * Design note:
 *   The tags appear inside expanded rows (sub-table of vendor prices).
 *   A site must be selected for distance/closest to be computed.
