## 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

## Summary
- align the multi-community rail with the content surface and balance
its visible 10px side gutters
- center Mobile pairing, start sessions on demand, and keep retry states
inside the QR area
- reveal the QR code and copy action with 250ms motion and use the
standard loading spinner
The rail was centered within its own box, but the adjacent sidebar added
another 11px to the visible right gap. Mobile pairing also started
before user intent, which could leave an idle session waiting for EOSE.
## Validation
- `pnpm -C desktop build:e2e`
- `pnpm -C desktop test` — 3,516 passed
- `pnpm -C desktop exec playwright test tests/e2e/community-rail.spec.ts
--project=smoke` — 19 passed

## Summary
- render mobile pairing QR codes locally with Wallet-inspired styling
- hide the raw pairing URI behind a matching copy button
- add focused rendering and dialog coverage
## Test plan
- desktop lint and 3,489 desktop tests
- focused pairing dialog Playwright test
- decoded the rendered QR back to the exact pairing URI
