-- Raise the default per-guest upload rate from 10/hour to 100/hour.
--
-- Rationale: guests routinely upload a burst of 10-20 photos at once (phone
-- multi-select). At the old default of 10/hour a real guest's first burst was
-- throttled — surfaced by the 2026-07-18 load test. 100/hour comfortably covers
-- several bursts across an event while still bounding abuse.
--
-- Only bump installs still on the old default; an admin who deliberately set a
-- different value keeps it (migration 005 seeded 10; this UPDATE is scoped to '10').
UPDATE config SET value = '100' WHERE key = 'upload_rate_per_hour' AND value = '10';
