CastStrip (a show's page) and PlexInfo (a title's page and the player's overlay) each drew the
cast carousel by hand, and the copies had drifted: the gap, lazy pictures, the name's tooltip, the
initial's size. Both now render CastRow, which takes the overlay's white-on-art palette as a tone;
each caller keeps its own frame and heading. A DOM test holds the palette per variant (seen red
with the tone wired to "panel"). jscpd over the shipped code: 1 clone >= 10 lines -> 0.
