/* ==========================================================================
   Timeline Chart — stacked columns, one series per project

   The plot area and the x-axis are separate rows on purpose. They used to be
   one column per month containing both the bar and its label; because the
   labels are vertical text their height varies with the month name, and the
   columns were bottom-aligned, so every month's baseline sat at a slightly
   different height. Splitting them means the baseline is the bottom of a
   fixed-height plot and cannot move.

   Gridlines and their tick labels are positioned by value inside that same
   plot box, so "$0" is the baseline rather than an approximation of it.

   Series colours: validated for CVD separation and >= 3:1 contrast against
   the white card surface. Slot order is the safety mechanism — re-run the
   palette validator before changing it.
