/**
 * PrintifySign — Inspiration Feed Styles
 *
 * File:    assets/inspiration/inspiration.css
 * Phase:   v2.0 Phase 1.3 — Feed Rendering
 *
 * All selectors scoped under `body.psd-inspiration-active` (set by the
 * Phase 1.1 template via body_class filter). This prevents:
 *   1. Inspiration styles leaking into other pages
 *   2. Other plugins/themes accidentally inheriting our rules
 *
 * Mobile-first: base styles target phone. Media queries layer on tablet
 * and desktop columns. Pinterest-style masonry-feel grid via CSS Grid
 * with implicit row tracks.
 *
 * Premium signage aesthetic:
 *   - Neutral background (warm off-white)
 *   - Cards: rounded corners, soft shadow, hover lift
 *   - Typography: system stack for clean reading
 *   - Buttons: dark accent against light card surface
 *   - Category pill: subtle, top-right of thumbnail
