The previous fix made the nav card and content column exactly equal
height, but the two boxes' TOP EDGES were already aligned all along —
what actually looked "off" was that the nav's first item text sat
~12px lower than the content heading/Save button, because Tabler's
default list-group-item padding (1.25rem) is sized for a standalone
list card, not a compact sidebar nav.
Verified with the same pixel-measurement technique as the previous
fix, against the real markup rendered in a browser: before, the nav's
first-item text center sat at y=95.5 while the content heading/button
center sat at y=84 (both card tops already matched at y=64). Tightening
this list-group's own item padding to 0.5rem (scoped via its own
--tblr-list-group-item-padding-y CSS variable, not a global override)
brought the nav text center to y=83.5 — 0.5px off target, imperceptible.
