- JWT stored in HttpOnly, Secure, SameSite=Strict cookie — JS cannot
read the token at all; SameSite=Strict prevents CSRF without tokens
- Non-sensitive user payload returned in response body and stored in
localStorage for UI purposes only (not usable for auth)
- Add POST /api/auth/logout endpoint that clears the cookie server-side
- Add SECURE_COOKIES env var (default true) for local HTTP testing
- Extract login.html inline script to login.js (CSP compliance)
- Remove Authorization: Bearer header from API calls; add credentials:
include so cookies are sent automatically
- CSP script-src includes unsafe-inline to support existing onclick
handlers throughout the app

- nginx: add X-Content-Type-Options, X-Frame-Options, X-XSS-Protection,
and Referrer-Policy headers on all responses; rate limit /api/auth/login
to 5 req/min per IP (burst 3) to prevent brute force
- frontend: add escHtml() utility to api.js; use it on all notes fields
across dashboard, log, history, flock, and budget pages to prevent XSS
- log.js: fix broken loadRecent() call referencing removed #recent-body
element; replaced with loadHistory() from history.js
- schemas.py: raise minimum password length from 6 to 10 characters
- admin.py: add audit logging for password reset, disable, delete, and
impersonate actions; fix impersonate to use named admin param for logging
- main.py: add startup env validation — exits with clear error if any
required env var is missing; configure structured logging to stdout
