- HorizontalScrollRow arrows bump 32px → 40px on coarse pointers
  (touch screens) for finger-friendly hits; mouse pointers unchanged.
- AlphabeticalGrid divider letter is now <h3> so screen readers
  announce it as a section heading. Margin reset to preserve layout.
- Modal overlay gets p-4 so max-w-md modals stay inside the safe
  area at 375px viewport. Covers all routes that use the shared
  <Modal> component (discover track-confirm, quarantine
  typed-DELETE, users password-reset, etc.).
