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.
