Frontend context

Read ai/shared.md first. This file only covers frontend-specific rules.

Project Context

Stack: vanilla PHP templates in views/templates/, plain ES JavaScript in public/js/, no framework, no build step. Cypress 15 for E2E. Entry point: public/index.php (Slim app); page templates are rendered via the existing templating layer.

Code patterns

Look at existing pages (home.php/home.js, text.php/text.js, today.php/today.js) for reference before writing anything
Templates: views/templates/<page>.php, one file per page
Page JS: public/js/<page>.js, one file per page, paired with the matching template
Testing: Cypress E2E only, mirror existing cypress/e2e/*.cy.js style (note: this project uses .cy.js, not .cy.ts)
Imports / script tags: keep at the top of the file
Variable names: explicit, descriptive (e.g. text not t)

Pre-commit

No JS formatter or linter is configured yet; format manually for consistency with surrounding files. (TODO: wire up format/lint when added.)

Note on commit granularity

Frontend changes are often a template plus its page-level JS counterpart - commit them together as a single logical unit, per the "one logical change per commit" rule in shared.md.

LLM anti-patterns

Constructs LLMs default to that this project forbids on the frontend.

Anti-pattern	Forbidden	Required
Short variable name	`t`, `n`, `res`, `req`, `e`, `el`, `ev`	`text`, `node`, `response`, `request`, `submitEvent`, `element`, `clickEvent`
Em dash in code/comments	`// loads texts — owner only`	`// loads texts - owner only`
Inline `<script>` in templates	`<script>doStuff()</script>` in a `.php` template	put logic in `public/js/<page>.js`, load via `<script src=...>`
Hardcoded admin URLs in user-facing JS	`fetch('/api/admin/...')` from a non-admin page JS	call user-scoped endpoints from user pages, admin endpoints only from admin pages
Cypress test logging in as the wrong role	`cy.loginAsAdmin()` in a non-admin spec	match the role to the page under test (`loginAsUser` for `/home`, `/texts`; `loginAsAdmin` for `/admin/*`)
`cy.request` in E2E tests	`cy.request('/api/...')` to set up state or assert	tests must exercise UI - drive via `cy.visit`/`cy.get`; if seeding is needed, add it to backend seed data

When generating code, scan the diff for these patterns before writing it to disk.
