-- Per-user queue preferences
-- =============================================================================
-- Lets each user hide specific queues from their own dashboard widgets
-- (notably the Queue posture heatmap). Presence of a row = that user has
-- hidden that queue. Absence = visible.
--
-- Independent of the global company_scope filter — that affects KPI counts
-- for everyone, this only affects what an individual user chooses to see.
