   DataQ — Dark theme (planned post-v1)
   v1 ships LIGHT. This file lays the foundation so dark mode flips
   with a single attribute and ZERO component changes — every override
   below remaps the SEMANTIC layer (and the surface/border scale aliases
   components read), never the components themselves.

   Activate:  <html data-theme="dark">   (or on any subtree).
   Auto (optional): see the prefers-color-scheme block at the bottom —
   commented out so v1 stays light until the team opts in.

   CONTRACT: components must reference semantic tokens (--bg-card,
   --text-primary, --border, --surface-*, --status-*-bg, …), never raw
   scale hexes. The light system already follows this; keep it that way
   and dark mode is free.
