/*
 * First-party grid -- Bootstrap 5.3's flex grid, restricted to the 60 grid classes
 * this site actually uses, with Bootstrap's exact selectors, breakpoints (sm 576,
 * md 768, lg 992, xl 1200, xxl 1400) and container max-widths (540 / 720 / 960 /
 * 1140 / 1320px).
 *
 * Part of the Bootstrap removal (PR 1 of 4). Bootstrap's CSS is still loaded and this
 * file is loaded after it; every declaration below restates Bootstrap's own, so the
 * cascade outcome is identical either way.
 *
 * The only deviation: Bootstrap's `--bs-gutter-x` / `--bs-gutter-y` mechanism is
 * reproduced under the first-party names `--gutter-x` / `--gutter-y` (same 1.5rem /
 * 0 defaults, same `calc()` expressions), so `.row > *` padding and `.row` negative
 * margins match Bootstrap exactly while owning no `--bs-*` name.
 *
 * The used set is computed by the same grep as utils/utilities.css -- see that file's
 * header -- and re-checked by core/tests/test_first_party_utilities.py.
