/**
 * Resale guardrails — scaffold only, no resale UX shipped yet.
 *
 * Per the 2026-05-12 dream-team verdict on "should WhatsMyStyle help
 * users resell closet items": HOLD until three guardrails are in place.
 *
 *   1. Circularity check — an item is eligible for a resale nudge only if:
 *        - it's been in the closet ≥ 90 days, OR
 *        - the user has confirmed "I've worn this >5 times", OR
 *        - the user has confirmed "this no longer fits/I will not wear again"
 *      Goal: prevent the app from accelerating fast-fashion churn.
 *
 *   2. Repair / recycle FIRST — before showing any sell-this CTA, the user
 *      must dismiss two options:
 *        a) repair_link  — link to a local tailor/cobbler (Google Maps
 *           Places query "tailor near me" or "cobbler near me")
 *        b) recycle_link — link to a textile take-back program
 *           (Patagonia Worn Wear, Eileen Fisher Renew, For Days Take-Back,
 *           local Goodwill / textile recycle dropoff)
 *      Only after the user dismisses BOTH do we surface the sell CTA.
 *
 *   3. Privacy limits — resale events are EPHEMERAL. We don't write to
 *      outfit_picks, we don't write to duels, we don't update the taste
 *      vector. We log only the local-time + closet_id + action verb to
 *      data/resale-events.jsonl for the user's own export — never the
 *      server's analytical use.
 *
 * Until the UX ships, this module just exposes the eligibility check +
 * resource links so the rest of the codebase can reason about it.
