/* CandleBrain KB -- front-end library styling.
 *
 * Matches the site's own homepage design system exactly, verified with
 * real rendered screenshots (not guessed): cream/peach page background,
 * white rounded cards with a soft icon-circle + amber heading + pill
 * CTA button, clean sans-serif throughout (no serif anywhere on this
 * site), soft offset drop shadows. Colors/shadows are pulled from the
 * theme's own CSS custom properties (--wp--preset--*) wherever possible
 * so this plugin automatically stays in sync if the site's brand colors
 * ever change, rather than hardcoding a competing palette.
 */

/* The theme renders its own page title ("Maker's Library") for any page
   that embeds [cbkb_homepage] -- but the shortcode's own Hero section
   already renders a proper <h1>, so the theme's copy is a redundant,
   unstyled duplicate sitting above it. Scoped to .cbkb-front, which only
   exists on shortcode pages or this plugin's own templates (and those
   never render this theme block at all), so this never hides a title
   anywhere else on the site. Dropped by accident during the 1.6.0 CSS
   rewrite; restored here. */
