/* Step number — a small notch centred on the thumbnail's top edge.

   Quiet on purpose. 26 of these are on screen at once, and the LABEL is what
   names the place; the number is secondary metadata and has to read that way
   or the strip becomes a field of dots. So: no white disc, no drop shadow, no
   bold weight. It takes the panel backdrop's own dark tone, which makes it
   read as a notch cut out of the card rather than a sticker applied on top,
   and the numeral is muted white rather than pure.

   The active card's number goes full white — hierarchy through one small
   contrast step instead of decoration on all 26.

   Sits OUTSIDE .room-card__thumb on purpose: that element carries the
   greyscale/brightness filter, which a child would inherit. */
