/* ============================================================
   WikiPress Child Theme - Custom Styles
   ------------------------------------------------------------
   Add your CSS overrides below. This file loads AFTER the
   parent theme's stylesheet (assets/css/main.css), so anything
   you write here wins over the parent without needing !important.

   The parent exposes reusable CSS custom properties on :root.
   The cleanest way to re-brand is to override those variables.
   Common ones (see parent assets/css/main.css for the full set):

     --wikipress-primary        Link / accent color        (#0645ad)
     --wikipress-primary-hover  Link hover color           (#043a7a)
     --wikipress-text           Body text color            (#202122)
     --wikipress-heading        Heading color              (#000000)
     --wikipress-bg             Page background            (#ffffff)
     --wikipress-bg-off         Off-white background       (#f8f9fa)
     --wikipress-border         Border color               (#a2a9b1)
     --wikipress-font-content   Article font stack         (Georgia serif)
     --wikipress-font-ui        UI font stack              (system sans)
     --wikipress-font-size      Base font size             (16px)
     --wikipress-content-max    Article max width          (780px)
   ============================================================ */

/* ---- Example: re-brand the accent color -------------------
