/* ============================================================
   <BrandMark /> — xmesh logo lockup.

   Owns the canonical brand glyph (three nodes routing to a single
   hub) and the wordmark. Three sizes:
     sm — 28px chip · sidebar header
     md — 40px chip · generic placement
     lg — 96px chip · brand showcase / about pages

   Pairs with components/brand-mark/index.jsx. The glyph is a single SVG
   that renders at any size — only the chip dimensions change.
