/*
 * Theory.toys CSS Manifest
 *
 * This manifest file imports all stylesheets in the correct order using Sprockets directives.
 * CSS precedence follows the standard cascading order - styles declared later will override
 * earlier ones, depending on specificity.
 *
 * Structure:
 * 1. Base - Foundational styles (reset, colors, typography)
 * 2. Layout - Page structure and grids
 * 3. Components - Reusable UI components
 * 4. Toys - Toy-specific overrides
