This keeps the visible note area stable when changing editor font size. It anchors the rich-text viewport before the font-size update and restores it after layout settles, so zooming shows the text getting larger or smaller without losing your place.

Adds /secret markdown blocks that store passphrase-protected secrets as helix-secret fences and unlock in the editor. Uses WebCrypto PBKDF2-HMAC-SHA256 with 600k iterations plus AES-256-GCM with salt, nonce, and AAD-bound metadata because it is dependency-free, portable to simple JS/Python decryptors, and supported by browser/webview WebCrypto. Tradeoff: PBKDF2 is not memory-hard like Argon2id/scrypt, so protection depends on strong passphrases and the high iteration count.

Adds editor scroll room after the final line so users can focus the active writing area without inserting blank lines. Ctrl+End moves to the document end and scrolls into that workspace; plain End keeps native line-end behavior. Presentation-only except cursor movement; does not mutate note content, mark dirty, or affect autosave.

Fixes keyboard navigation after creating a collapsible section: pressing Enter or Tab from the section title now moves the editor selection into the section body (`Start writing...`) instead of leaving the cursor in the title.
Validation: `COREPACK_ENABLE_AUTO_PIN=0 pnpm build`.
