   `display: contents`, so the <ul> is transparent to layout — column and gap
   overrides MUST target the `.grid` div, not `> ul` (setting them on the <ul>
   is silently ignored). The homepage has exactly four numbered cards: pin them
   to a balanced 2x2 on desktop and a single column on narrow screens. The
