   Text Repeater — tool layer over base.css
   base.css supplies reset, type, forms, buttons, chips, badges, panels, tables,
   header, footer, focus rings. This file adds the accent and only what is
   unique to this tool.

   Accent — sky blue, measured against base.css surfaces (WCAG relative
   luminance):
     dark  #61a8ef  7.52:1 on --bg   6.94:1 on --surface   7.79:1 on --bg-sunk
     light #084f96  7.84:1 on --bg   8.17:1 on --surface   7.18:1 on --bg-sunk
   Both clear the 4.5:1 text floor on all three surfaces in both themes.
