/**
 * Curated list of Angor supporters shown on /supporters.
 *
 * Deliberately opt-in: only list people/organisations who are happy to be
 * shown. Discover the raw list (privately) with:
 *   node ~/.config/skatespots/angor/angor-backers.mjs
 * → writes ~/.config/skatespots/angor/work/backers.json (npub + txid).
 * The amount = the sum of the investment transaction's Taproot stage outputs
 * (per-backer `amount` = 99,000 sats here; total matches the app's "0.00198 BTC").
 *
 * Entries:
 *   - people:  { npub, amount }  → links to their profile; add `name` to override
 *   - shops / orgs: { name, logo, url, amount }  (logo: PNG/WebP, transparent, ≥200px)
 *   - hide identity:   { anonymous: true, note }
 *
 * ⚠️ Don't add someone without their consent — a backer's npub + "backed this
 * project" is new, linkable information even though the key is public.
