/* ---- matrix build view — deliberately echoes print.css's typography and table language ----
   Both tables use table-layout:fixed + width:100%, so columns fill the available width and
   shrink together as more get added (more preset columns, more stops) — the whole point being
   that the sheet stays on one screen without horizontal scroll for a typical column count.
   Each table also carries a computed inline min-width (see matrix-view.js) as a floor below
   which columns would stop being usable — only past that point does the .panel's own
   overflow-x:auto kick in as a fallback, which is the expected, graceful degradation for an
   unusually wide sheet, not the normal case. */
