Applies Anthony Fu's conventions for JavaScript and TypeScript projects: file organization, explicit imports, Vitest style, @antfu/ni, @antfu/eslint-config with antislop, Knip, tsdown and a single ci script, mirroring the antfu/starter-ts template for new projects.

Testing practices for Vue apps: Vitest and Vue Test Utils, black-box component tests, flushPromises for async code, helpers for testing composables, Pinia stores, async components and Teleport, avoiding snapshot-only tests, and Playwright for end-to-end testing.
