/* ============================================================================ Resonant Labs — shared design system ---------------------------------------------------------------------------- Extracted from the NeuroRad.ai mockup set (hub / landing / atlas / training / brookes-brain) and reconciled with the DEPLOYED Atlas palette in ../../assets/styles.css. This file is the single source of truth for the marketing + product-shell surfaces under /site. It does NOT style the deployed Atlas SPA (that stays on assets/styles.css, untouched). Theming model: one dark "Resonant" base; each product sets an accent by putting a theme class on (.theme-resonant / .theme-neurorad / .theme-brain / .theme-chatty). Components read --acc, so the same markup re-skins per product. ============================================================================ */ :root { /* ---- surfaces ---- */ --bg: #07080a; --ink: #eef1f6; --ink-soft: #cfd4de; --muted: #8b909e; --faint: #5c616d; --line: rgba(255, 255, 255, .08); --line-strong: rgba(255, 255, 255, .15); --glass: rgba(255, 255, 255, .03); --glass-2: rgba(255, 255, 255, .055); --panel-solid: #101216; /* ---- family accents (one company, distinct products) ---- */ --resonant: #a78bfa; /* parent hub — violet */ --neurorad: #2e90ff; /* flagship clinical — neon blue */ --chatty: #f5b642; /* AI literacy — amber */ --brain: #34d3a6; /* pro workflow — clinical teal */ /* neon-blue support tones (match deployed Atlas) */ --accent: var(--neurorad); --accent-2: #5aa8ff; --accent-ink: #9cc6ff; --accent-deep: #1e5fd0; --link: #5aa8ff; /* teal support tones */ --brain-2: #5fe0bd; --brain-deep: #1b8f70; /* ---- evidence-grade palette (luminous on black; matches Atlas grade.js) ---- */ --g-strong: #34d399; --g-strong-bg: rgba(52, 211, 153, .12); --g-moderate: #60a5fa; --g-moderate-bg: rgba(96, 165, 250, .12); --g-weak: #fbbf24; --g-weak-bg: rgba(251, 191, 36, .13); --g-consensus: #c084fc; --g-consensus-bg: rgba(192, 132, 252, .13); --g-spec: #9aa0ac; --g-spec-bg: rgba(154, 160, 172, .12); --g-unresolved: #fb7185; --g-unresolved-bg: rgba(251, 113, 133, .13); /* ---- type + motion ---- */ /* No external font requests (keeps CSP tight + matches deployed Atlas, which is system-font only).
