/* ============================================================
   DownyPet · Store storefront site — design system "Verdant Clean" (v1 rework)
   Direction (locked by Cao on 2026-08-22): green + clean minimalism
   Design narrative: natural / clean / restrained / professional. Generous whitespace, thin lines, light borders, minimal decoration,
   departing from the prototype LumiPaws' coral-orange and the previous all-purple layout.
   Palette: forest green primary + near-white canvas + light green base + warm amber (rating, very sparing) + semantic red (danger)
   Typography: single sans-serif Plus Jakarta Sans (bold headings + tight tracking, clean and modern)
   Unified component classes (.btn/.card/.badge/.field/.sidebar-link…) for easy migration to Blade templates
   ⛔ P0: sitewide no emoji icons (use unified inline SVG) / no purple-pink gradients / no hardcoded colors (only #fff/#000)
   ============================================================ */
