   Mouse Sensitivity Converter — tool layer over base.css
   base.css supplies reset, type, forms, buttons, chips, badges, panels,
   tables, header, footer, focus rings, .stat/.stat-value, .field-label.
   This file adds the accent and only what is unique to this tool.

   Accent — pale yellow-green, measured against base.css surfaces (WCAG
   relative luminance):
     dark  #efe161  14.1:1 on --bg   13.0:1 on --surface   14.6:1 on --bg-sunk
     light #766d1e   5.1:1 on --bg    5.3:1 on --surface    4.6:1 on --bg-sunk
   Both clear the 4.5:1 text floor on all three surfaces in both themes.
