/**
 * ily.dog Design System v3.0 — "Grid Paper"
 * 
 * Dark theme: modular dashed containers on grid paper.
 * Think blueprint notebook meets modular workspace.
 * 
 * Key design principles:
 *   - Background: dark paper with subtle grid lines (CSS gradient)
 *   - Containers: dashed borders (not solid) — everything is a module
 *   - Accents: warm amber/gold (like pen on graph paper) + cool blue
 *   - Corners: crisp (no border-radius on containers, slight on interactive)
 *   - Typography: monospace-friendly, technical feel
