The baseplate works.

One hand-authored template. The engine only pours in the words, photos, and colors. Every element re-colors itself to the site's palette. Two sites below, same template, same parts, different palette.

Morning, Michael. This is the bridge we talked about, proven. Tap each one. Look at how the salon (light) and the film studio (dark) are the exact same template with the exact same drop-in parts, just a different palette poured in. Nothing was redesigned. The engine dressed a finished design.
The two proofs

Copper Fox Salon light palette

Warm editorial. Green accent flows from the header through every part.

Atlas Films dark palette

Deep ink, violet accent. Same template, same parts, all re-colored automatically. Note the FAQ at the bottom, that socket was an empty hole on the salon site.
What this proves

1. Hand-authored, not improvised. The layout is the design. The engine never guesses arrangement anymore.

2. Sockets are real LEGO holes. The salon's bottom socket is left empty on purpose (you can see the hole). On Atlas I dropped an FAQ into that same hole and it just filled and adapted.

3. Every plug obeys the palette. Fan cards, stats band, FAQ, gallery, button, footer, all re-colored from the header's colors with zero manual work. That was your one must-have.

This is template 1 of 100. It scales by authoring more baseplates (one per header family) and growing the parts library. Each part is written once and adapts everywhere. When you're up, tell me: keep proving more templates, or wire this in as the real engine and start authoring the hundred.
