/* =========================================================
   shared/css/markup.css
   Visual styles for all classes emitted by renderMarkup()
   and the ref/popup system.

   All visual properties use CSS variables with sensible
   fallbacks. No scoped selectors. No hardcoded values.

   Variable contract — set per-context in surface.css or
   per-app in :root (see surface.css and app stylesheets):

     --nwm-size     font-size for markup content  (default: 1rem)
     --nwm-text     body text color               (default: #444)
     --nwm-muted    secondary / muted text color  (default: #888)
     --nwm-accent   ref / accent color            (default: #c9a84c — gold)
     --nwm-brand    subheading / section color    (default: var(--nwm-accent))
     --nwm-border   separator / border color      (default: #e0e0e0)
     --nwm-surface  popup / card background       (default: #faf7f2)
     --nwm-shadow   popup box-shadow              (default: 0 4px 16px rgba(0,0,0,.08))
     --nwm-focus    focus ring color              (default: var(--nwm-accent))

   Fallback values match the reading-surface defaults set by
   surface.css, since that is the primary rendering context.
