feat(web): point the hero at the services, and say the offer in the hero

The primary button sent every visitor to /products, a sixteen-item grid mixing
services for sale with consumer games we publish. A buyer looking for commerce
work landed among mobile games. It now goes to /services, which is where the four
pillars and the terms actually are.

The subhead also now states the offer, which the site made five times deeper in
and never on the front page. Worded as a qualified option rather than a headline:
revenue share is something web services CAN be provided on, not the studio's
model for games, crypto tooling or the education work.

The H1 is deliberately unchanged. "Precision Engineering for Everyone" names no
buyer and no category, but replacing it is a positioning decision rather than an
engineering one, and it stays open. The two events landed in the previous commit
mean the next attempt at it can be measured rather than argued.
