Home page sections: workflow, what comes off the press, proof sheets, requirements, colophon

Parent

Add the rest of the home page's text sections, in the order set in #61, around the press line.

Day shift / third shift: the human's Day shift uses Matt Pocock's skills interactively (grill → spec → tickets). Then thirdshift's third shift uses headless copies of them (implement → review → PR). Use the Glossary's definition of Day shift.
What comes off the press:
- what "ready for review" is backed by: mergeable, CI passing, reviewed against the documented standards and the issue;
- findings the agent chose not to fix are listed as Unaddressed findings in the pull request body;
- a Failed run's work is still pushed, and its pull request goes back to draft.
Proof sheets: Treat SIGHUP like SIGINT and SIGTERM #25 (SIGHUP), Numbered Issue branches after a merged or closed PR #21 (numbered Issue branches), CI watching, CI-fix Repair and the Repair cap #22 (CI watching and Repair) and Pre-flight checks #16 (pre-flight). Each is drawn as a proof sheet with its title, the issue it closed, and one line on why it's worth a look, linked to the pull request.
Requirements and platforms:
- claude, gh, git;
- Rocky Linux 9.8+, Ubuntu 24.04.3+, WSL2 with Ubuntu 24.04+, and macOS Tahoe 26.5.2+ on Apple Silicon;
- for WSL2: keep repositories on the Linux filesystem, and WSL1 isn't supported.
Take these from the README so the two agree.
Colophon: set in Playfair Display italic, with the owner's text word for word from Spec: thirdshift.app, a site that shows how the factory works #61. Don't edit it.

Use Glossary terms exactly, and don't use the word "ticket" on the site.

All four sections appear in the order Spec: thirdshift.app, a site that shows how the factory works #61 sets, styled with the shared tokens.
The four proof sheets link to the right pull requests and issues.
The requirements and platforms match the README.
The colophon matches Spec: thirdshift.app, a site that shows how the factory works #61 character for character.
Screenshots at laptop and phone sizes are attached to the pull request.
