BUG-046 (CRITICAL): getUsageStats() now accepts apiKey param and returns
only that key usage instead of all users. Route passes req.apiKeyInfo.key.
BUG-047: Added visible Copy button to Pro key success page in billing.ts.
BUG-048: Added class="open-email-change" to Change Email links in all
HTML pages so the JS modal opener can find them.

Inline script was already extracted to swagger-init.js (BUG-004/005).
Helmet defaults allow style-src unsafe-inline and font-src https,
so Google Fonts and inline styles work without custom directives.

- Add CSP directives to allow inline scripts/styles and Google Fonts
- Add email-change.ts route with rate limiting (3/hr) and verification

- Add email-change route to index.ts with CORS support
- Launch BROWSER_COUNT separate Chromium instances (default: 2)
- Each with PAGES_PER_BROWSER pages (default: 8, 16 total)
- Round-robin distribution across browser instances
- Independent restart scheduling per browser
- Updated health endpoint to show per-browser stats
- docker-compose: added BROWSER_COUNT and PAGES_PER_BROWSER env vars
Investor Directive 1: Key recovery now shows key in browser after email verification code.
- Removed sendRecoveryEmail function entirely
- Recovery endpoint returns apiKey in JSON response (shown once in browser)
- Added full recovery modal UI (email → code → key displayed)
- Added "Lost your API key?" links throughout signup flow
Investor Directive 3: Rate limits adjusted to match server capacity.
- Global rate limit: 100/min → 30/min (server handles ~28 PDFs/min)
- CORS: recover routes now restricted to docfast.dev origin
- POST /v1/recover: request recovery code
- POST /v1/recover/verify: verify code, receive key via email
- Key sent via email only (not in API response) for security
- Rate limited to 3 attempts per hour
- Non-enumerable: same response whether email exists or not
- DKIM-signed emails via postfix/opendkim
- Signup now requires email verification before API key is revealed
- Verification token sent via email (Resend) with console fallback
- GET /verify?token=xxx shows API key in styled HTML page
- Handles expired (24h), invalid, and already-verified tokens
- Frontend modal shows 'check your email' instead of key
- Keeps existing rate limiting
- Added CORS middleware allowing docfast.dev origin
- Added app.set('trust proxy', 1) to fix ERR_ERL_UNEXPECTED_X_FORWARDED_FOR
- The rate limiter was crashing on every proxied request through nginx
- Added /v1/signup/free endpoint for instant API key provisioning
- Built unified key store (services/keys.ts) with file-based persistence
- Refactored auth middleware to use key store (no more hardcoded env keys)
- Refactored usage middleware to check key tier from store
- Updated billing to use key store for Pro key provisioning
- Landing page: replaced mailto: link with signup modal
- Landing page: Pro checkout button now properly calls /v1/billing/checkout
- Added Docker volume for persistent key storage
- Success page now renders HTML instead of raw JSON
- Tested: signup → key → PDF generation works end-to-end
