 * v3 — Layout rewrite
 * All original class names are preserved so existing markup/JS keeps working.
 * The only structural addition is one new, purely additive wrapper class,
 * `.apcb-content`, which now holds the toolbar/carousel/pagination that used
 * to live directly under `.apcb-main`. See the notes above `.apcb-main`
 * below for why this replaces the old CSS Grid sidebar hack.

/* ==========================================================================
   LAYOUT
   `.apcb-app` = main column + summary column (unchanged: still a simple
   two-column grid, that part was never the problem).

   `.apcb-main` = category sidebar + `.apcb-content` (toolbar, carousel,
   pagination). These two are now plain FLEX SIBLINGS, not a CSS Grid with
   one child spanning rows the others implicitly populate.

   WHY THE OLD LAYOUT CREATED EMPTY ROWS
   The previous version made `.apcb-main` a grid with
   `grid-template-columns: max-content 1fr; grid-auto-rows: min-content`,
   pinned `.apcb-categories` to `grid-column: 1 / grid-row: 1 / -1`, and
   pushed every *other* child to column 2 via a blanket `.apcb-main > *`
   rule. That only produces a correct result if the grid's implicit
   row-track count and content stay perfectly in sync with the sidebar's
   row span — but the toolbar/grid/pagination are DOM children built and
   re-rendered independently by JS (`.apcb-grid` gets its innerHTML replaced
   on every AJAX category/page/search change). Any mismatch between the
   number of auto-generated row tracks and what the sidebar was spanning
   left column 2 without a track to sit in for that row, while column 1
   (the sidebar) kept reserving the space — which reads as a blank white
   band before the toolbar and another before the carousel. It was a timing
   / track-count coupling bug baked into the architecture, not something a
   spacing tweak could fix.

   WHY THE NEW LAYOUT CANNOT DO THAT
   There is no shared track system left to desync. `.apcb-categories` and
   `.apcb-content` are two independent flex items placed left-to-right (or
   stacked top-to-bottom on small screens) by the flexbox algorithm, which
   only ever looks at the actual rendered size of each item — never a
   pre-committed grid of rows. Re-rendering the contents of `.apcb-content`
   (grid swap, pagination swap) cannot leave a gap next to the sidebar
   because the sidebar was never sharing a row with it in the first place.
