/* =====================================================================
   modules/sd-presentations/index.css
   SD Presentations -- both themes via platform CSS custom properties.
   No hardcoded colors. CSS custom properties only.
   All selectors scoped under [data-module="sd-presentations"].

   Platform tokens used (all defined in platform/styles.css):
     --bg            page/app background
     --panel         primary surface (sidebar, toolbar, drawer)
     --panel-2       slightly elevated surface
     --input-bg      form input background
     --text-primary / --text-secondary / --text-tertiary
     --border        subtle border
     --border-strong stronger border
     --accent        brand accent color
     --accent-soft   accent with low opacity tint
     --shadow / --shadow-sm / --shadow-lg
     --row-hover     subtle hover highlight
     --overlay-bg    modal scrim
     --error         error/destructive color

   Module-local token --sdp-page-bg: the artboard slide background must
   always render as white (it represents a physical printed page). Declared
   as a CSS custom property on the module root so the hex value lives in a
   declaration block, not in a rule body.
