   Tables: the spacer-gap column model.

   Column widths and inter-column gaps are computed by table-engine.js (one
   engine, mounted on every `table.data`, per the standard's "central, never
   per page" enforcement rule): it measures each column's widest unwrapped
   cell, then either distributes leftover container width as equal padding
   between columns, or leaves natural widths and lets the table scroll
   sideways inside `.table-wrap` when content doesn't fit. This stylesheet
   only supplies the parts that don't depend on measurement: the header
   look, edge insets, alignment, row density, sticky header, and the frozen
   first column / right-edge cue used once a table actually scrolls.
