Remove editor browser test parallel locks

 - Selector-contract remediation requests must be handled repo-wide across all relevant test files (`Web.Tests` and `Web.UITests`), not as partial per-file cleanups.
 - Browser and editor acceptance tests must be stable against seeded demo content, user-entered text, and import filename variations: assert invariant UI behavior, use shared fixtures/constants, and wait on explicit ready or completion signals instead of incidental page titles, transient text, or race-prone intermediate chrome.
 - Editor browser tests that mutate document content must create or import an isolated script for that scenario and edit that script only; do not point multiple mutating tests at the same seeded library script or shared draft state.
+- Do not keep `NotInParallel` on browser-test classes that already use isolated browser contexts and isolated writable scripts; parallel locks need a concrete documented shared-resource conflict, not legacy caution.
 - When the user asks to stabilize failing tests or gather a red baseline, prioritize reproducing the failures, capturing the failing test list, and fixing the suites before spending time on git history, commit hygiene, or other bookkeeping.
 - Repo-wide quality audits and agent-generated review handoff artifacts must be written as root-level task files so other coding agents can pick them up quickly; do not bury those temporary audit results under `docs/` unless the task is explicitly about durable product documentation.
 - Repo-wide cleanup and review passes must explicitly inventory forbidden implementation string literals, `MarkupString` or raw-HTML UI composition, duplicated JS/CSS patterns, architecture-boundary drift, and `foreach`-driven test scenarios that should become isolated TUnit cases.
