Link-as-Document Share URL Generator

Following the Tiny Little Office idea (HN 50096142): your document is compressed (DEFLATE) and encoded into the URL fragment, which browsers never send to any server — privacy by architecture, not by policy. The recipient opens the link and the /doc viewer renders it instantly, fully client-side. This generator takes a title, lightweight Markdown content (# headings, - items, [ ] tasks), header fields and one of five templates (note, letter, checklist, meeting minutes, resume), then produces the share URL plus a downloadable plain-text fallback. Optional password protection encrypts the payload with AES-256-GCM using a PBKDF2-derived key (150,000 iterations) — decryption happens only in the recipient's browser after they type the password; the password itself never travels with the link. Every link is graded for portability: ≤ 2,000 characters is safe anywhere (chat, email, QR), ≤ 8,000 works in browsers and most apps, longer links are browser-only — honest guidance, because messengers can truncate long URLs even though browsers accept up to ~2 MB. Honest limits: a lost link is a lost document, and encryption guards against strangers reading a leaked link, not against anyone who has the password.
