   BsHierarchicalMatrixTable — component styles
   FE-035 slice 4. Component-scoped prefix: bs-hmx-
   2026-06-04: aligned to the portfolio table standard (#overall-performance):
   gray --bg-inset header, bold/UPPERCASE/centered headers, full subtle cell
   borders, zebra/group tint, right-aligned mono numerics. Switched off the
   private --color-* namespace (light-only fallbacks) onto the canonical app
   tokens, so the table also renders correctly in dark theme.
