Problem

PREVIZ_PALETTE has 8 colours, and figure_colour(index) wraps with index % 8. In a Setup with more than 8 subjects, two figures get the same colour (noted in #171 and #175). The composed prompt then says that two subjects are "the red figure in <Video 1>", so H3 can't tell them apart. The filmmaker can't tell them apart in Blender either.

Options

Grow the palette (12 or more distinct colours), and wrap only after that.
Give the 9th and later subjects no colour, leave them out of the prompt's colour mapping, and warn on the Shot.
Warn in the previz panel, or refuse "Open in Blender", when the Setup has more subjects than colours.

This needs a decision before it is ready for an agent.

Acceptance criteria

No two subjects in a Shot's scene spec and composed prompt share a colour, or the filmmaker is told when they do
Scene spec and prompt composer tests cover a Setup with more subjects than palette colours
