Summary

Remove the extra 12px horizontal padding from mobile-web assistant text so paragraphs align with their timestamp and the Show response toggle. Keep the transcript gutter, list indentation and bottom spacing.

Type and Areas

Type: bug fix / UI

Areas: mobile-web assistant message styles.

Motivation / Impact

Assistant paragraphs began 12px to the right of their timestamp, including expanded history and streaming replies. The Harmony-style override added this padding after the Markdown styles. The transcript now owns the common horizontal gutter.

Verification

• pnpm --dir src/mobile-web run test:chat-transcript-browser — both browser suites passed.
• pnpm run build:mobile-web — passed.
• git diff --check — passed.
• Real Chrome component rendering and screenshot review at 390, 768 and 1280px: paragraph, timestamp, response toggle, expanded history and streaming text all start at x=16px. Previously text started at x=28px. List indentation remains 24px, with no horizontal overflow.

Reviewer Notes

This changes one mobile-web style rule, with no wire, persistence or host behavior changes. Verification used local browser fixtures; no live SSH, Relay, Peer Device or Detached Dispatch connection was exercised.
