Problem
.icon-btn is 38×38px (chat.css ~76–80) and .send-btn is 36×36px (~579) — below the WCAG 2.5.5 / Apple HIG 44px and Material 48dp minimum touch targets. The drawer row ✕ is 30×30px.
Suggested fix
Increase hit areas to ≥44px (padding or invisible tap targets) while keeping the visual size if desired.
