 ## Context
 
-The browser-mode component test suite (`vitest.client-coverage.config.ts`) enforces Istanbul coverage thresholds across `lines`, `functions`, `branches`, and `statements`. The `branches` metric was set to 80%, but the codebase sits at approximately **75%** — below the gate — causing every CI run of `unit-tests` and `coverage-flake-probe` to fail on this check alone, even when all tests are green.
