What it does

A list of 2-5 facts: bold label + one supporting line. The licence number is mono (a printed-artifact detail, per the type rules) and links to the CSLB licence detail page (set href yourself for other states). data-since recomputes "17 years" from the current year so the page never goes stale.

When to use

Under the hero or beside the quote form on CALL pages.

Hard facts only: a licence # checked on CSLB, an insurance line the owner confirmed.

Don't

Claim licensed, insured or bonded without proof (skill rule: ask the owner).

Icons in circles over each fact (anti-slop: icon-card rows).

More than 5 facts, or repeating the rating if Rating line is already under the CTA.

Reduced motion, no JS, accessibility

No motion.

No JS: the same text (years as written at build time; lookup link only if you set href).

A real list with an aria-label; link text is the licence number itself.
