# T02: Added inline SVG logo mark (cyan arc + dot from favicon) to header brand area with flex alignment

**Added inline SVG logo mark (cyan arc + dot from favicon) to header brand area with flex alignment**

## What Happened

Read the favicon.svg mark geometry (arc path + circle at #22d3ee). Added the same paths as an inline SVG inside a new .app-header__logo span before the brand text in App.tsx, with aria-hidden for decorative semantics. Updated .app-header__brand to flex layout with gap for logo/text alignment. Added .app-header__logo sizing styles at 24px. Build passes cleanly with zero errors.

## Verification

npm run build succeeds (0 errors, 57 modules). grep confirms app-header__logo class in both TSX and CSS, inline SVG present, #22d3ee accent color present. All 10 slice-level checks pass (favicon assets in dist/, meta tags in dist/index.html).
