/*
  Disable MudBlazor's default uppercase on buttons.
  Rationale: quiz options and other dynamic content can be Turkish
  (e.g. "izin vermek"), and the browser's CSS text-transform: uppercase
  is driven by the document lang attribute. With lang="en" it applies
  English uppercase rules and produces "IZIN VERMEK" instead of the
  proper Turkish "İZİN VERMEK". Rendering labels as-authored (sentence
  case from Razor) sidesteps the i/İ locale mismatch entirely and looks
  cleaner.
