/* Per-level button alignment (buts_align in panel).
 *
 * Works across the three layouts .buttons can be in:
 *   - flex-direction:column (default, no grid-* class)
 *   - grid-2 / grid-3 (grid-template-columns)
 *
 * Container-level justify/align-items are kept as defaults for legacy
 * flex behaviour, but the *real* alignment is done on the .btn itself
 * via align-self + justify-self. That's necessary because:
 *   - grid cells default to justify-self:stretch, which makes .btn
 *     fill the entire column and completely hides justify-items on
 *     the parent.
 *   - flex column items honour align-self to move across the main
 *     (horizontal) axis.
 *
 * Width override is required too: without it the button stays 100% of
 * its cell/flex track, and alignment has nothing to do.
