- 06b/06c: third column label is now "Book & Library" with the heading
"The book and the AiBook.fun library" (was "Cloud" / "Do it yourself,
online"). Same size, cover image unchanged.
- 09 header renamed to 09-header-book-library-and-aibook-fun.png with the
title "Book & Library and AiBook.fun" (was "Cloud and AiBook.fun").
- three_ways() builds the grid from a list of columns so a fourth bucket can
be added later without a CSS change; three-column output is unchanged.
- Contact sheet and README updated.
The book and library tiers ($19 Early Bird eBook, $25 eBook plus updates,
$47 eBook plus 12 months of AiBook.fun, $55 signed paperback, $85 Collector's
Bundle) were grouped under "Cloud". WeOwn Cloud is a separate product, so the
bucket is now "Book & Library" everywhere. Sentences that called Cloud the
do-it-yourself path now describe the Book & Library tiers plainly. Prices,
dates and other content are unchanged. The .docx is regenerated from the
fixed Markdown with v2/build_docx.py (same page map, 36 pages).
