/* "Blog post card" layout: a dark, editorial-style card (no real unit
   photos exist yet, so the "background image" is a darkened gradient
   built from each unit's own accent color instead of a stock photo)
   with a numbered index, and a colored circle that expands from the
   top-right corner on hover — clipped by the card's own overflow:hidden
   so it reads as a smooth circular wipe, not a jump-cut. --unit-color
   (set inline per card, from includes/church-unit-visuals.php's
   existing per-unit color map) and --unit-card-time are the two CSS
   custom properties driving the color and animation timing, so both
   can be tuned from one place without touching the hover rules. */
