/* ==========================================================================
   SLU Bento Box Widget
   A bento grid of self-contained cells. Each cell carries its own col/row span;
   grid-auto-flow: dense packs them with no ragged holes. Pure CSS, no JS.

   Balance model:
   - --slu-bento-cols  : column count (set per breakpoint by the Columns control)
   - --slu-bento-row-h : fixed row height (grid-auto-rows) so a 2-row box is
                          exactly twice a 1-row box, gaps included
   - per cell: --slu-bento-col-span / --slu-bento-row-span

   Span clamping: there is no native span-minmax(), so we clamp the column span
   with min(span, cols). A box can therefore never span past the current column
   count when the grid narrows — the classic "last column overflows the grid"
   bug. At 1 column everything becomes a clean stack automatically.

   Hello Elementor reset overrides: bare <a> and heading colours carry
   !important (see CLAUDE.md "Elementor / theme CSS").
