Changed
- Toolbar collapses related tools behind one button. Text/Markdown/Sticky now live in
a Text group and Image/Stock in a Media group. Each main button re-runs the tool
you last picked from it; a small corner caret opens a flyout to switch. Sticker, Link and
Vault stay as standalone buttons. Reuses the existing shapes-flyout pattern (
ToolGroup), trimming the row from 11 buttons to 8 — easier to scan and friendlier on mobile.
