     The 32px horizontal padding looks right on a wide desktop but on
     a phone it puts the inner content ~32px from the screen edge,
     while sibling sections that happen to use 16px end up ~16px from
     the edge — producing the visible misalignment seen on My Tasks
     (task card sits ~16px further inset than the toolbar / stat
     tiles above it).
     Normalize every common top-level panel selector to 16px on
     mobile so the whole page stays on the same column. !important
     because per-page styles often use the `padding: Ypx 32px` shorthand
     at the same specificity, so a non-important rule would lose. */
