Testing & QA

Practical guide to testing web applications with screen readers for comprehensive accessibility validation.

Run e2e tests relevant to the current changes. Selects `.feature` files based on `git diff`, runs `just test-quick`, and skips e2e when changes are server-only with no UI impact. Triggers on "run tests", "test this", "check if it works", "e2e", "test the changes".

Do a task end-to-end — implement, PR, CI loop, ship. ONLY invoke when the user explicitly types `/do` or `$do`; never auto-select from a natural-language request, even one that sounds like an end-to-end task.
