Inserts the tile at the front of the arcade grid with a 'new' badge,
matching sibling markup exactly, and recomputes the footer count from
the live tile list rather than trusting the hand-maintained number.
Refuses to run twice so a re-run cannot duplicate the tile.

Four directions per tile (neon box art / vector side art / amiga comic /
80s airbrush) generated on the farm, plus the picker page and the installer
that ships chosen art and its risograph hover b-side.
Recipe rules, all learned the hard way against the existing covers:
tiles render 172-240px so silhouette and colour are all that read; the page
draws every title in HTML so art carries no lettering (the old covers baked
in garbled type); busy interiors smuggle text back via album sleeves and go
muddy small, so it is one hero subject per card.
