/* Phase 8.7.4 — iOS auto-zoom guard on the chat input.
   Mobile Safari zooms-in any focused input below 16px. The desktop
   chat panel design uses 12px to fit the dense chat layout, but on
   mobile we bump to 16px specifically to defeat the auto-zoom. The
   visual change at <=480px is negligible because the chat panel is
   already full-width with its own mobile breakpoint stack. */
