-- Rewarded-video caps: the anti-abuse ceilings on free rewarded credits per user, per
-- day and per hour. VK Mini App ads expose only a client-side watch result (no
-- server-to-server verify), so a rewarded credit is client-attested; the caps bound a
-- forger who skips the ad and calls the credit endpoint directly (the daily cap bounds the
-- total; the hourly cap smooths a burst). Chips-per-view already exists
-- (rewarded_payout_chips, default 0 = rewarded inert until the owner sets it). All are
-- config, tuned in the admin without a release. Additive columns only — applies forward via
-- goose with no data rewrite (no contour wipe), and an image rollback ignores them.
