+/*
+ * Shared expiry chip — used by My Shares (link expiration), Trash
+ * (remaining lifetime), and any future expiry display.
+ *
+ * Produced by `formatExpiryChip(value)` in `core/formatters.js`.
+ * Six tiers map a date to an urgency colour:
+ *
+ *   never     → null value           — neutral, infinity icon
+ *   normal    → > 30 days away       — neutral grey
+ *   caution   → 8–30 days            — soft amber
+ *   soon      → 2–7 days             — soft orange
+ *   urgent    → today or tomorrow    — soft red
+ *   expired   → past                 — deeper red, warning icon
+ *
+ * Colours are pastel/tinted on purpose: the chip should give an
+ * at-a-glance cue without competing visually with surrounding content.
