/* Photo mysteries (#425) — "who is this?" on a photo, and the one gentle
   place where every open question waits.

   Two visual states on the marker:
     - OPEN mystery  → a warm terracotta "?" badge, always visible, on every
       surface the photo appears on. It's a question the family is asking, so
       it never hides behind a hover.
     - ASK affordance → quiet and dark, revealed on hover/focus on a mouse, and
       ALWAYS visible on a touch viewport (MOBILE/TOUCH PARITY RULE — there is
       no hover to reveal it with). */
