/* ---- Data table (Categories, Budgets) --------------------------------------
   Deliberately its own layout, not .responsive-table: that pattern always
   card-stacks (by design, see above) which is right for a wide multi-input
   row but turns a long category list into a very long scroll of tall cards
   on desktop. These tables' columns are narrow enough (badges/pills instead
   of full-width inputs) to read comfortably as a real table above the phone
   breakpoint.

   table-layout: fixed with percentage columns (rather than sizing from
   content, like a normal table would) is the actual fix for the
   horizontal-scroll bug the categories page shipped three different patches
   for: the table's own width can never exceed its container regardless of
   viewport width, so there's no in-between size left to overflow at — the
   same "no breakpoint to mistune" principle .responsive-table already uses,
   applied to a real table instead of forcing card-stacking everywhere.
   Column widths are per-table (.categories-table / .budgets-table below)
   since each has a different column count; everything else is shared. */
