 # Completed Steps
 
+- 2026-08-10: every interactive control now meets the 44x44 CSS px minimum tap
+  target (`.pin-btn`, `#interval-select`, the debug-log label and, on narrow
+  viewports, `#pause-btn`). The pin button's hit area grows via matching
+  negative margins, so its layout footprint and row density are unchanged
 - 2026-08-10: per-host status line wraps below the 768px breakpoint instead of
   forcing horizontal page scroll at 320px
 - 2026-08-09: `Dockerfile.backend` reworked to the mandated Go multistage
