/* ==========================================================================
   ENSDF.HTML

   A toolbar, then the main area (the chart of nuclides, or the decay-chain
   chart) beside a panel of tabs with a drag handle between them. Colours
   are the tokens in kvot.css, so the page follows the theme toggle; the few
   below are the chart's own. Class prefix: nz-.

   The chart's cell colours are not here: they are drawn on a canvas, and
   live in ensdf-core.js (PALETTE) with the reasoning beside them. The
   decay-mode colours are the documented categorical slots of the dataviz
   palette, assigned by an exhaustive search over the pairs of modes that
   touch on the chart (beta-minus against electron capture, alpha against
   fission, electron capture against proton emission ...): the assignment
   used clears the normal-vision floor in both themes, and its worst
   colour-blind pair sits in the floor band -- which is why every cell also
   carries its mode in the hover card, the legend and, zoomed in, its label.
