// Tests for 20260826130300_suppress_trial_for_byra_companies.sql (WL-10):
// the company-creation trial trigger (trg_seed_trial_capability_grants /
// seed_trial_capability_grants) must skip companies attached to a byrå team
// (already entitled via the team-scoped partner grant) while personal-team
// and teamless companies keep the 30-day trial exactly as before.
//
// The trigger is AFTER INSERT ON companies and reads NEW.team_id, so plain
// inserts through the pool exercise it on every creation path.

// Full PAID set (20260818170000); must stay in step with
// lib/entitlements/keys.ts PAID_CAPABILITIES. Sorted: trialGrantKeys()
// orders by capability_key.
