"""assets.py — the not-tonight generation manifest (docs/VENUES.md §6).

One entry per sprite the three new venues need. `run_batch.py` walks this list;
nothing here executes anything itself, so it stays readable and diffable.

Two routes, per the A/B recorded in docs/SPACES.md:

  flat  — flux draws the finished sprite. For things with no volume: signage,
          screens, boards, wall art, backdrops. Flux picking its own camera does
          not matter when the object IS a flat plane.
  mesh  — flux draws a clean PRODUCT SHOT, TRELLIS.2 reconstructs it, Blender
          renders it from the ONE fixed ortho camera every prop shares. For
          anything with volume. The product shot is deliberately NOT a top-down:
          TRELLIS reconstructs best from a clear view of the object, and the
          game's camera angle is applied at render time by `rake`.

`rake` follows the house rule the hard way round (LANEHANDOVER, FABLE-SOLO-25):
**60° for low and wide, ~76° for tall.** Lowering the rake for a tall object to
"see more face" is wrong — a tall object is already all face, and at 55° it
renders as a featureless slab.
