v1.4.14 — Add a designed front/back cover, wired into the PDF
Designed a cover (navy/gold, “EXPERIMENT” badge) in Canva and added it
to the repo (images/cover.png, images/back-cover.png), shown on
the root README. Wired both into the compiled PDF as full-bleed
first/last pages via eso-pic’s shipout hook. Two build bugs found
and fixed along the way, both in build/build_latex.py so they
survive the next full rebuild: \newgeometry issuing its own
\clearpage internally consumed page 1 as a blank leaf when called as
the very first document command, pushing the cover to page 2; and
forcing both width=\paperwidth and height=\paperheight
independently stretched the image to the page’s aspect ratio instead
of preserving it. Verified with full clean rebuilds (zero errors) at
each step.
