New domain `browser` under frontend/functions/ with 6 Playwright helpers: - pw_launch_browser: chromium + context + page bootstrap with storageState support and baseUrl navigation. - pw_kanban_login: authenticates a Page against /api/auth/login; sets the kanban_session cookie via shared storageState; verifies login page no longer visible after navigation. - pw_drag_drop: human-like pointer drag (mousedown + activateOffset + stepped move + mouseup) compatible with @dnd-kit/core's 8px activation threshold; supports hoverMs for time-based dropzones. - pw_keyboard_sequence: ordered focus/type/press/wait steps for scripting realistic input flows (typing then arrow-key navigating autocompletes). - pw_wait_predicate: thin wrapper over page.waitForFunction with friendlier defaults and custom error messages. - pw_assert_class: poll-based assertion that a Locator has/lacks a CSS class within a timeout; useful for visual-state checks. Each function ships with vitest tests (5-8 cases each) covering both happy and error paths, plus self-documenting .md (Ejemplo + Cuando usarla + Gotchas + frontmatter with params/output schema). Adds frontend/functions/package.json with `"type": "module"` so consumers can ESM-import the .ts files from anywhere in the registry (Playwright's tsx loader respects nearest package.json). Capability page docs/capabilities/playwright.md documents the group with a canonical end-to-end example, frontiers, prerequisites, and gotchas. Index updated. First consumer (issue 0088): apps/kanban requester-input.spec.ts. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
