Previous attempts (e50631c, 6f2bea9) zeroed .container's pt-3 and the
first child's mt-3, but the right column was still sitting ~32px lower
than the sidebar. Reason: Bootstrap 5 ships .pt-3 and .mt-3 as
margin-top: 1rem !important / padding-top: 1rem !important. My
overrides without !important lost the cascade and never took effect.
Match Bootstrap's specificity by adding !important on both rules.
