What Was Built

13-page dark-theme PDF release report for Claude SEO v1.9.0. Generated via scripts/release_report.py using WeasyPrint + matplotlib. Covers: Pro Hub Challenge contributions, architecture evolution, review score progression, security audit findings, DataForSEO cost guardrails, and Challenge v2 announcement.

Stats: 13 pages, 1.53 MB, 4 charts, 7 screenshots embedded, logo visible on title page.

Brand: Space Grotesk font, #0A0A0A background, #E07850 accent (rust-orange), #111111 cards, #2D2D2D borders. Matches SVG Diagram Style Guide.

Bugs Fixed

Bug	Root Cause	Fix
Logo not rendering	Filename has double space: “AI MArketing hub pro logo with white text.png”	Corrected path in generate_report()
file:// images not loading	Spaces in paths not URL-encoded	Added _file_url() helper with urllib.parse.quote()
Review checker false WARNs	Checked URL-encoded paths against filesystem	unquote() before Path.exists()
Title page empty bottom half	Fixed height:297mm + sparse content	Removed fixed height, added “In This Report” card
Contributor card page-break orphans	display:table-cell is atomic in WeasyPrint	Replaced two-column layout with stacked blocks
Architecture scripts table orphaned	7-row table split across pages	Replaced table with paragraph
Security highlight box orphaned	Orphaned after large table	Merged text into intro paragraph
Chart page mostly empty	Chart too small relative to page	Increased figsize height, moved chart first in section

WeasyPrint PDF Lessons

1. file:// URIs must be URL-encoded — spaces become %20. Use urllib.parse.quote(path, safe="/:@"). When reviewing paths extracted from HTML, use unquote() before Path.exists().
2. display:table-cell is atomic — WeasyPrint cannot break a table-cell across pages. For content that might span pages (contributor cards, multi-row content), use stacked block elements (<p> + <ul>) instead of two-column table layouts.
3. Fixed height causes empty space — height: 297mm on a div with sparse content leaves blank below. Use auto height + generous padding instead.
4. Tables that overflow: replace with paragraphs — if a table consistently orphans its last rows, a <p> with inline <code> spans is more reliable.
5. Chart figsize controls page fill — matplotlib figsize directly affects how much of the page the chart occupies. Increase height to fill empty space after a chart.
6. max-height: 165mm on .chart-container img — good default for charts on their own section page.
7. Check filenames carefully — “AI MArketing hub pro logo with white text.png” has a double space between “hub” and “pro”. Path.exists() is the fastest way to catch this.
