/*
 * ProducerLens shared design tokens.
 *
 * Extracted from dashboard.html / admin.html / login.html to eliminate
 * drift between surfaces and to give new surfaces (agent drawer, command
 * palette, clusters, leaderboard, etc.) a single source of truth.
 *
 * Slogan: "No more spreadsheets". The visual vocabulary here is deliberately
 * magazine/product-dashboard rather than ops-console — elevated surfaces,
 * legible monospace for data, playful accents on state.
