Increase type size ~28% for readability; commit PDF build tooling

Site: body 14px -> 18px, h1 28px -> 36px via style.scss theme override
(em-based elements scale with body). PDF: body 11.5pt -> 15pt, headings
scaled proportionally; now 87 pages. Build script and stylesheet moved
to tools/ so the PDF is regenerable from the repo.
