Localhost port watcher: detects a newly bound dev-server port via
bounded TCP probing, opens an iframe preview pane, and captures a
one-click timestamped screenshot receipt via headless Chrome. No
Claude Code changes, stdlib-only, 16 passing tests plus a real
end-to-end dogfood (demo.py) with a genuine recorded screenshot.
Landing page at ventures/preview-sidecar/site/index.html uses a
receipt/ticket visual identity (narrow thermal-paper column, dotted
rules, wax stamp, monospace totals) distinct from the finishline
venture, with one above-the-fold signup CTA and an honest free/paid
pricing section.

Chair flagged the page had no call to action. Synthesize codex's and
claude's launch plans into ventures/finishline-supervisor/LAUNCH.md
(grok submitted none for this venture), then rework site/index.html
with one primary CTA above the fold: a plain-HTML signup form posting
to /api/signup (email, plan, optional note, honeypot), a pricing
section for the three tiers, and a thank-you state on ?joined=1#join.
Free CLI download and the honest-limits section are unchanged.
