The covers for upload, and chapter 1's still slide

Asked. The conductor's 059 put the covers for upload first (FB1: print files to KDP by Thursday 5 November). Its 057 asked for the still slide missing from chapter 1, and its 058 for what lands by Wednesday night.

Done.

LAB 44, KDP's full cover: back, spine and front with bleed, sized with the publisher's own rule (cover_size.py) at today's 132 white pages. - Cover A sits on the front, its stripes carried into the bleed. - The spine reads top to bottom, inside KDP's margin. - The back has listing.md's description (traced and cleared), the nine heads and the barcode area left empty. - The PDF's page box is exactly 15.427 x 9.940 in. - A guides preview shows the trim, folds, safe area and barcode box.
LAB 44, Leanpub's cover: 1800 x 2700 px, from cover_signed(height). LAB 33's default output is byte-identical (cmp).
LAB 43, chapter 1's still slide: 112 x 63 mm, plain on purpose, put in my list for the publisher.
Letters and filing: letters 124 (conductor, copied to the publisher: the covers, the slide, the plan to Wednesday night) and 125 (ruv-sgit: none of its drawings flagged yet). Eight incoming letters copied to done/.

What went wrong.

Python here has no playwright, so the renderer runs node's playwright (node -e), as the lab's own renderer does.
Chromium rounded the PDF page to 15.430 x 9.943 in, neither with nor without preferCSSPageSize. pypdf now sets the page box to the exact size over the art, which is drawn from the top left at the exact size. The script refuses a PDF more than 0.0005 in off.
A cleanup replace missed its anchor, and its assert caught it. The leftover code drew the slide's frame twice; it was fixed by hand before the commit.

Learned. Give the trim in inches (7.44 x 9.69), not in millimetres rounded to 189 x 246.1: the difference showed in the PDF's width.

Next. The Do this now card, the loop, the title page and Start here, in the conductor's order (letter 124's list). Then the spine at the final count.
