 * Smart upsell tile — Dashboard home, rendered by balance-upsell-tile.js
 * Sits just below the main balance widget when runway dips below 14 days.
 *
 * Three severities, mirroring user-balance-pill.css:
 *   --info     — runway 7..14 days (soft heads-up, no urgency).
 *   --warning  — runway 3..7 days (yellow, action recommended).
 *   --critical — runway < 3 days (magenta, action needed soon).
