/* Gauntlet shell chrome — aurora viewfinder.

 * tokens.css; there is no color literal in this file by design (ADR-0005,
 * enforced by dashboard/tests/test_design_tokens.py).
 *
 * Wave-1 scope: the page shell only — nav, aurora atmosphere, cards, empty
 * states, bottom status strip, login. Capability-specific styling arrives in
 * its own feature-owned file alongside the capability (ADR-0002).
