/* ============================================================
   BOMAtlas Atlas Shell — the education-atlas app chrome.
   Light, clean, map-first. Used by / and the education shells
   (/trade-schools/, /universities/, /community-colleges/,
   /private-colleges/, /education/).

   Segment hues are palette-validated for the light basemap
   (lightness band, chroma floor, CVD separation, contrast).
   Type identity is never color-alone: list rows, the legend,
   and the selection card all carry the type label as text.
