/* ==========================================================================
   HomeRP base stylesheet (#78)
   ==========================================================================

   Loaded after the vendored Bootstrap and before the design-system layers.
   Its job is narrow: normalise the document, set the type system from the
   tokens, and style the two pieces of chrome Blazor itself owns (the boot
   loader and the unhandled-error bar). Page and component patterns live in
   ui.css (#80), data display in datadisplay.css (#81) and forms in forms.css
   (#82); the anonymous shell in anonymous.css (#83).

   Rule: no colour, radius or spacing literal in this file — only tokens.
