/* ==========================================================================
   Seizure Management course figures (components/seizure-figures.js)

   Built on the shared figure frame and tokens in teaching-figures.css
   (.brf, --viz-*): one frame per figure, solid hairline axes, series colors
   on marks only. Text keeps the ink colors; where a label sits on a colored
   segment the segment is a light tint of the series color with a solid edge,
   so the label stays readable in both themes. The charts are HTML, so their
   labels keep a legible size on a phone, and each one reflows to its own
   width (container queries), not the window's.
