   Drop this into wwwroot/css/ and link it in App.razor AFTER the MudBlazor
   stylesheet so these rules win:

     <link rel="stylesheet" href="css/ph-components.css" />

   These classes are the source of truth for layout and visual detail.
   Use them on plain elements or on MudBlazor components via the Class="…"
   parameter. DO NOT rebuild these in MudGrid/MudItem — the grid classes here
   exist specifically because MudGrid's flex items do not stretch children,
   which is what causes uneven card widths.

   Correct markup:
     <div class="ph-kpi-grid">

/* ── Column width cap + title wrapping ──────────────────────────────────────
   `display: -webkit-box` (a former "3-line clamp" attempt here) breaks a
   <td>/<th>'s table-cell layout — it takes the cell out of the browser's
   table column-width algorithm entirely, which auto-table-layout uses across
   EVERY row in that column, not just this one. That's what was collapsing
   every column in the whole matrix down to near-zero width (found 2026-08-03,
   reported as "attribute matrix page is screwed up"). white-space: normal +
   overflow-wrap: anywhere already lets a long Title wrap across lines within
   the 190px cap without leaving table-cell layout — no clamp needed. */
