Subject: [PATCH] ci(make-pdf): matrix copy-paste gate on Ubuntu + macOS
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Runs the combined-features P0 gate on pull requests that touch make-pdf/
or browse's PDF surface. Installs poppler (macOS) / poppler-utils (Ubuntu)
per OS. Windows deferred to tolerant mode (Xpdf / Poppler-Windows
extraction variance not yet calibrated against the normalized comparator —
Codex round 2 #18).
