🔧 OTP code generator

Generates TOTP/HOTP one-time codes: enter a base32 secret + algorithm (SHA1/256) + digits (6/8) + period (s); TOTP mode shows the current code with a remaining-time countdown, HOTP mode uses a counter. HMAC uses the browser `crypto.subtle` (HMAC SHA-1/256), falling back to a pure-JS HMAC-SHA1 if unavailable. base32 decode + RFC 6238/4226 dynamic truncation. No network, runs in your browser.
