## Summary
- Add separate **Font size** and **Conversation density** controls in
Appearance.
- Use a 13 / 14 / 15px conversation text ramp for Smaller / Default /
Larger while scaling interface typography through a shared virtual-rem
system.
- Keep layout geometry fixed while typography changes, and compose Cmd
+/- text zoom on top of the selected preference.
- Let Compact, Comfy, and Spacious control conversation row spacing plus
paragraph and list rhythm in Markdown content across Buzz.
- Preview font size and density together with click-and-drag comparison;
interrupted scrubbing restores the saved preference.
- Synchronize preferences across open Buzz windows, including full
local-storage clears during sign-out or dev reset.
- Promote the segmented control to shared UI and make Settings rows
adapt to their card width.
## Validation
- `just ci`
- 4,965+ desktop unit tests across the final merged branch
- 1,465 mobile tests through the full repository gate
- Focused Playwright coverage for font-size/density independence, drag
preview cancellation, Inbox geometry, thread rendering, keyboard zoom,
and cross-surface typography
- Fresh E2E build against the final merged branch
