   HOMEPAGE v2 QUICK-ACCESS / LEARN / CLASS CARDS
   These are <a> elements with block-level children
   (h2/h3/p) and were never given an explicit display,
   so browsers default them to "inline" - an inline box
   around block children fragments into a separate,
   unstyled box per wrapped line instead of one solid
   card. That's the "box disappears on mobile" bug: more
   text wraps at narrow widths, so the fragmentation (and
   the missing background/border/shadow look) becomes
   obvious there, even though the same broken markup
   affects desktop too.
