/* ============================================================
   AI Prompt Vault — Front-End Shortcode Styles  v2.0

   Theme Integration Strategy
   ──────────────────────────
   All colors reference CSS custom properties that most modern
   WordPress themes (Twenty Twenty-One and later, GeneratePress,
   Astra, Kadence, Blocksy, Neve, OceanWP, Hello / Elementor, Divi)
   define on :root.  We cascade to sensible generic fallbacks so
   the plugin looks reasonable even on older themes that do not
   expose those variables.

   Common variable names used across themes:
     --color-primary / --wp--preset--color--primary
     --color-text    / --wp--preset--color--foreground
     --color-bg      / --wp--preset--color--background
     --color-border  / --wp--preset--color--contrast
     --global-font-family / --font-base

   Divi-specific (kennedy media / client sites):
     --et_headings_font / --et_body_font_family
     primary color is usually set as a class, so we pull from
     --et_primary which Divi writes when custom colors are active.
