aneurinandClaude Sonnet 5 5c8f2dbf07 Un-hard-wrap all Markdown documentation
Every prose paragraph and list item was manually wrapped at ~80-100
columns; joined each back into a single line. Headings, table rows,
and fenced code blocks are untouched -- tables already had one row per
line, and wrapping inside a code fence is the code's own formatting,
not something this applies to.

Also fixed two pre-existing typos this surfaced (both from wrapping
without leaving the space that was actually intended): a missing space
in "{ challenge_id, options }" and a stray "+ TypeScript" that had
accidentally been written as if it were a new line, in web/README.md
and README.md respectively.

Code comments are explicitly out of scope for this -- left exactly as
they were.

# Architecture
A REST API in PHP 8 (Slim 4) over a single SQLite file, plus a Vue 3 + TypeScript PWA frontend. Auth is a bearer JWT, obtained via a magic link or a passkey (see [docs/api.md](api.md)) — there's no session store or cookie.
## Backend layout
```
public/index.php Front controller
src/bootstrap.php App wiring and route definitions
src/Support/Config.php Environment-driven configuration
src/Support/Database.php PDO/SQLite connection
src/Auth/JwtService.php Issue/verify JWTs
src/Auth/AuthMiddleware.php Bearer-token authentication
src/Auth/SessionPayload.php Shared user + session JSON shape
src/Mail/ Mailer interface, SMTP/mail()/log transports, EmailVerifier
src/Http/JsonErrorHandler.php Uniform JSON error envelope
src/Http/Controllers/ Request handlers (Auth, EmailVerification, Passkey, Project, Card, CardStatus)
src/Repository/ Database access (User, EmailVerification, Passkey, WebAuthnChallenge, Project, Card, CardStatus)
src/Support/Validator.php Request-body validation helper
migrations/*.sql Schema, applied by bin/migrate.php
Dockerfile Multi-stage: Node frontend build + PHP 8.3/Apache runtime
(Alpine -- apk's own php83/apache2 packages, not a
from-source compile; ~90MB image)
docker-compose.yml Local stack: app (SPA + API) + Mailpit
docker/ Apache vhost (mod_rewrite, document root) + entrypoint
(runs pending migrations, then hands off to Apache)
web/ Vue 3 + TypeScript + Vite PWA frontend (dev on the host)
```
A `ProjectScopedController` base class centralizes "look up a project owned by the caller, or 404" for the controllers that need it (`Project`, `Card`, `CardStatus`). Every table a request can reach is scoped to the authenticated user one way or another — directly (`owner_id`/`user_id`) or via a project that is.
## Frontend
The Vue/TypeScript PWA lives in [web/](../web/) and is a separate concern with its own conventions (routing, state, styling, drag-and-drop). See [web/README.md](../web/README.md) for all of that — this document only covers the backend.
## Database
One SQLite file, migrated forward-only by `bin/migrate.php` from `migrations/*.sql` (each applied file is recorded in a `schema_migrations` table, so re-running is safe). See [docs/setup.md](setup.md) for how to run migrations, and [docs/history.md](history.md) for how the schema and the rest of the app got here.
