/* Static chrome for the Excel-like workbook preview tables (#166).
   Lives in wwwroot (not scoped CSS) because EPPlus emits the markup with
   raw class names — Blazor's scoped attribute selector can't reach
   classes on dynamically-generated <th> elements.

   Uses MudBlazor design tokens so the chrome adapts to the active theme
   (brand swap / future dark mode). EPPlus's per-workbook inline <style>
   block continues to carry the per-cell colors (epp-s1, epp-dxf1, etc.).

   The FluentUI overflow-tab overrides that used to live here were dropped
   post-#345 — MudTabs handles overflow without spawning a `+N` badge. */
