## Summary - Document prose (`--plan-body`) drops from 17px (`--text-lg`) to 15px (`--text-base`); h3 subheadings keep 17px. - Chat pane (left rail) message text, input, and markdown body drop from 15px to 13px (`--text-sm`). - Decisions pane (right rail) comment text also drops to 13px so both rails match, per design intent. - Updated stale token-role comments in `theme.css` and `styles.css` to reflect new usage.

## Test plan - [x] `bun test apps/web/src/tokens.test.ts` — 27 passing - [x] `bun scripts/check-tokens.ts` — tokens consistent - [ ] Visual check in browser
