Integrations got faces, the header got truly unified, and the notes box stays where you put it

Three improvements that shipped together:

• The Integrations page got its imagery: the Telegram, WhatsApp, Slack, and Discord marks in tinted tiles, plus icons for the MCP server, one-paste AI connect, the REST API, and webhooks — each card now scannable at a glance, with a little lift when you point at it.
• The homepage header genuinely matches the other pages now. It was one CSS layout subtlety apart — same parts, different frame — and the frame is now identical everywhere.
• The "my notes box snapped smaller" gremlin is dead. A thorough audit found the exact sequence — a background refresh rebuilding the panel right after a checklist edit, restoring only dragged heights and forgetting typed-content height — plus four sibling holes, including one that could quietly revert an edit made in the last second or two before a sync. All closed: your dragged height now survives reloads too, dragging smaller sticks instead of springing back, and background refreshes keep their hands off anything you have focused.
