The prompt behind this hero

Design the homepage hero section for this business and give it to me as a single HTML file I can open in a browser.

Business: {BUSINESS NAME}
What we do, in one line: {WHAT YOU SELL OR DO}
Who it's for and where: {YOUR CUSTOMERS AND TOWN OR AREA}
One true fact that builds trust: {E.G. YEARS TRADING, A REVIEW SCORE, A NAMED CLIENT, A GUARANTEE}
The one action we want: {BOOK, CALL, GET A QUOTE}

Before the code, in six lines or fewer, tell me the idea: the mood in one sentence, the three colours as hex codes, the two fonts, and why they suit this business and not any business.

Colour: two quiet colours (a background and a text colour, close to neutral) and ONE accent. The accent appears in two places at most: the button and one word or line of the headline. Pick an accent people wouldn't expect for this trade that still feels right once they see it. All text, including the button label, must pass WCAG AA contrast.

Type: one font pair from Google Fonts. A display face with character for the headline, a plain readable face for everything else, two weights at most for each. The headline should own the screen on a laptop; size it with clamp() so it still fits a 375px phone without breaking words.
