   Solara EF Internal — restyled to the solara.farm design system
   Cream surfaces + Springtide teal family. Sharp 4px corners,
   mono kickers, DM Sans display, JetBrains Mono numerics.
   PURE VISUAL RESTYLE — all IDs/JS hooks preserved.
   Chart/JS-facing tokens (--color-*) are mapped onto the new
   palette so Chart.js picks up teal-family colors unchanged.
