   رِماية — concept A «Midnight Velvet»
   ----------------------------------------------------------------------------
   Dark-luxury landing page. Near-black charcoal base (#0E0B14 → #1A1A1A) with
   deep-purple atmospheres; Electric #5C17FD and Violet #BB50F8 are used as
   LIGHT (glows, hairline highlights, thin gradients), never as flat fills.
   White text at 72%/52% opacity for body and meta.

   Palette and font rules: prototypes/admin/BRAND_NOTES.md · AGENTS.md §2.
   No hue outside the identity. No teal. One tiny green-free "done" tick uses
   Violet, and the completed state is marked with a violet check, per §2.
