- GET /link-preview?url= fetches the page on the server (https only,
SSRF-guarded like webhooks), reads Open Graph/Twitter tags, title,
description and icon from the head, loads picture and icon (no SVG) and
keeps them in link_previews (migration 6) for 7 days; readers' browsers
never contact the page. Off in the demo; 300 fetches per address in
15 minutes.
- Compact card above the bullet (icon, site, title, one line, small
picture); the duplicate link badge is left out.
- ✕ turns the address into [title](url), so hiding syncs with the note;
"Link-Vorschauen anzeigen" under appearance switches all off per device.
