Render explainer film B, 'The bank and the swarm', at full resolution in three aspects. Inputs (at .imd/reads/artifacts/): the six accepted engraved keyframes k1-bank … k6-press and the storyboard; the storyboard's pipeline is marketing/explainer/film-b/build_b.py in this repository (it built the animatic with stand-ins). Read marketing/explainer/BRIEF-B.md, the storyboard and marketing/explainer/RENDER-NOTES.md first.

Steps: (1) put the real keyframes in marketing/explainer/film-b/keyframes/.

(2) Bring the keyframes to life with your video tool, image-to-video from each keyframe with the storyboard's section 2 prompts, camera moves and negative prompt, clip lengths at least the shot lengths, K5 and K6 locked off: inspect every clip frame by frame and REJECT any clip that invents letters, numerals or glyph-like marks, drifts from the engraving style, adds objects or faces, or moves the K5 screen or the K6 sheet; a rejected clip is replaced by the storyboard's code-only fallback (the still with the push), never by a worse clip.

(3) Fix the two geometry errors measured in RENDER-NOTES.md: type the question and figure inside the REAL K5 screen field (x 589-1370, y 241-767) and corner-pin the assembled note onto the REAL tilted K6 sheet using corners you measure on the image. (4) Render 16x9, 1x1 and 9x16 with build_b.py and --music marketing/explainer/anthem/explainer-anthem.wav, judging engraving shimmer at full size.

The figure typed on the screen stays the storyboard's placeholder 1.2345 (it is not a price). The poster is the frame at 33.300 s (the note complete on the sheet). The README names, per shot, whether the picture is a generated clip (model, settings, seed) or the code fallback, and why.

Timing contract: 40.000 s at 30 fps, 1200 frames; HIT at frame 1095 = 36.500 s (two ivory frames, then the end card to 40.000 s); the music is marketing/explainer/anthem/explainer-anthem.wav from this repository, used from time zero with no gain change, fade or re-timing (it is mastered, its hit is at 36.500 and it is silent by 39.900).

Outputs: 1920x1080, 1080x1080 and 1080x1920, H.264 yuv420p High, AAC 48 kHz, +faststart, exactly 40.000 s, plus a 1920x1080 poster PNG. Check every file with ffprobe (codec, frame count, durations, the cut at 36.500) and redo any that fails. Do not change the timing, the captions, the layers or the end cards; every word on screen stays what the plates and lettered layers carry.

The README records the measured durations, cut times, render settings, and any limitation.
