/* Ported from the calfresh_interview_trainer.html prototype's inline <style> block,
   split out as part of the frontend/backend rewrite (ADR-0004). Login-screen and
   budget-banner rules are new; everything else is carried over unchanged.
   Re-themed to USWDS (U.S. Web Design System) tokens/components — worker-facing tool,
   not a public-facing .gov site, so no official banner, but same visual register:
   Public Sans, USWDS primary blue, square/minimal-radius components, high-contrast
   focus states. See devops/architecture for the ADR recording this decision. */
