Description: The official theme for Click and Solve (clickandsolve.com) — a minimal, professional companion theme built to pair with the Click and Solve Tools plugin. Provides the site header, navigation, footer, and base page layout; the plugin supplies the homepage, tool pages, category pages, and Business Guides content via its own templates (this theme's get_header()/get_footer() are what those templates call into).

 * DESIGN TOKENS
 * Mirrors the Click and Solve Tools plugin's own tokens (same variable
 * names/values) so the two never visually disagree, regardless of which
 * stylesheet's :root block the browser applies last. If the plugin's
 * Settings > Branding > Primary Color is ever changed, update the value
 * below to match for full-site consistency.
