web: print the shared frame's own labels on the QR recipe card

The card carried studio copy — SUNSET GLOW, a made-up warmth/grain/bloom line
and a creator handle borrowed from a testimonial — no matter which still the
arrows landed on. Stepping the frame changed the picture and the code but left
the text behind, so the card described a photo it was not showing.

The card now reads the frame's own labels: the tagline over the still and the
title and ISO/grain line under it are the ones the uploader saved with the
photo, the same three the film strip prints. The fabricated creator/imports
line goes with them, since nothing behind it was real.
