/* ============================================================================
   CHARAN REVIEW SYSTEM — Application Stylesheet
   ----------------------------------------------------------------------------
   Design language ported from the "worldcup2026" system:
     Barlow Condensed (structural display) / Inter (body) / JetBrains Mono (numeric)
     Frosted-glass surfaces, neutral zinc base, spring easing.

   Adapted for an HR review product:
     · Indigo brand accent drives focus, links and active navigation.
     · A 1–5 score ramp (red → amber → green) is a first-class token family.
     · A full form system — the reference app had none — built in the same idiom.

   Dark theme is a first-class citizen throughout.
   Korean is the primary content language: `word-break: keep-all` + Korean-aware
   fallback stacks are applied globally.

   SECTIONS
     A. Tokens
     B. Base / reset / shell atmosphere
     C. Layout
     D. Navigation
     E. Surfaces  (card, badge, button, stat, skeleton, divider, empty, toast, modal)
     F. Form system  (field, input, select, likert, checkbox-card, actions, progress)
     G. Data display (table, list, score-bar, score-ring, progress-steps)
     H. Motion
