Template:UI/button

Renders a styled button-link. Supports both internal wiki page links and external URLs, with primary and secondary visual variants.

Use page for internal links (e.g. Special:RequestAccount), or url for external links (e.g. a Brevo subscribe form). Provide exactly one. If both are set, url wins.

The style parameter chooses the visual treatment:

• primary (default) — filled progressive blue. Use for the main

 call-to-action on a page (e.g. mailing list signup, primary form).

• secondary — outlined neutral. Use for supporting CTAs that

 shouldn't compete with the primary action (e.g. "Request an account" next
 to a "Subscribe" button).

Styling uses Citizen-skin CSS custom properties with hex fallbacks so the button adapts to light/dark mode and degrades gracefully on other skins.

Parameters:

• page — internal wikilink target (mutually exclusive with url)
• url — external URL (mutually exclusive with page)
• label — button text (required)
• style — primary or secondary (default: primary)
