   G. TASK CONTROL — the live view's main panel

   danger red. Checked with the dataviz validator over ALL pairs, because a
   segment that is zero makes any two others touch: the worst normal-vision
   pair is 21.4 (floor 15). Band orange and blue were dropped here: orange
   beside yellow scored 14.9 and blue beside green 13.6. Green↔red is 7.8 for
   deuteranopes — legal only with secondary encoding, which is the 2px surface
   gap, the always-visible legend with counts, and the per-segment tooltip.
   Yellow and green sit under 3:1 against paper, so the counts are never

   Q. SMALL SCREENS
   1280: the side column of a record drops under the main one.
   1024: the rail becomes a scrolling strip of its links; filter trees move to
         the dropdowns in the filter bar, which exist on every width.
   760:  one column everywhere; the sub-bar stops sticking.
   390:  nothing scrolls sideways except a table inside its own box.
