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. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
