/*
 * SYFlow base stylesheet for the legacy Phase 1 landing page at /.
 *
 * Brand tokens follow syflow-brand v1.0:
 *   Synergy Navy   #1C294B
 *   Synergy Orange #E47135
 *   Deep Navy      #0F1834
 *   Cream          #F7F5EE
 *
 *   Display / wordmark: Jura 700, letter-spacing -0.01em
 *   UI body (English):  Inter
 *   UI body (Arabic):   IBM Plex Sans Arabic
 *
 * The React app at /app/ uses its own equivalent CSS (SYF-P2-T1).
 * Phase 2 will eventually retire this page in favor of the React app,
 * but for now both must look identical.
