mural-master: --estimate dry-run cost estimator (no-spend) — batch $ before approval [yolo Q2, local-only]
d43631e3d37dea330071f7bc9a797b74445842a2 · 2026-06-03 08:50:11 -0700 · Steve Abrams
Mirrors esrgan_tiled's level loop exactly (count_esrgan_calls + _tiles_1d) to
report per-mural + batch Replicate call count and $ without making any calls.
12x11ft / 12-mural batch = ~216 calls / ~$3.30. Lets Steve see the spend before
greenlighting the paid batch. self-test still green; compiles clean.
