/* ==========================================================================
   Data Lab stylesheet.

   Deliberately minimal: a neutral, near-blank light theme so contributors
   can take the design anywhere. All tokens live on :root; components
   reference the classes below via `class_=` props in app/.

   After editing, run `make manifest` so the stylesheet's cache buster
   updates.
