/* Estimate Flow — brand color tokens */
/* Single source of truth for all colors used by admin + customer portal.
 *
 * v3.22.0 — REPOINTED to the canonical SWG SaaS Design System
 * (docs/swg-saas-design-system.md). Estimate Flow is a SaaS-style
 * application (admin console + customer portal + CRM-like reporting), so
 * per the agency SaaS exception it adopts the SaaS palette (#2563EB
 * primary) instead of the marketing-brand electric blue (#38A8D8). The
 * electric-blue marketing accent is retained for email templates only,
 * which use hardcoded hex inline styles per Email_Template::COLOR_*
 * (email clients strip external CSS — that exception predates v3.22.0).
 *
 * Design philosophy: modern, professional, organized, premium, easy to
 * navigate, fast, consistent. Inspiration: ClickUp / Linear / Asana /
 * HubSpot / Harvest / Notion / Monday.com. Calm surfaces, one clear
 * primary color, white cards on a soft gray canvas, functional icons,
 * never more than one thing competing for attention.
 *
 * WCAG-AA discipline:
 *  - Bright "500-level" accents (#22C55E green / #F59E0B amber /
 *    #06B6D4 cyan / #8B5CF6 purple / #EC4899 pink) are DECORATION ONLY
 *    — icon-container fills, status dots, progress bars. NEVER body text.
 *  - For colored TEXT, use the *-dark variant (success-dark #15803D,
 *    warning-dark #B45309, etc.) which passes AA on white.
 *  - #2563EB primary passes AA on white (5.17:1) for text OR fill.
 *  - White on #2563EB is safe (5.17:1); white on #22C55E / #F59E0B is NOT
 *    (~1.7-1.9:1) — never put white text on those.
