   DESIGN SYSTEM GUIDE
   ===================

   ## Color Usage
   - Backgrounds: --color-bg (primary), --color-bg-alt (sections), --color-bg-dark (emphasis)
   - Text: --color-text (body), --color-text-light (secondary info), --color-text-muted (metadata/labels)
   - Accent: --color-accent (headings, active states, CTAs), --color-accent-light (hover states)
   - Border: --color-border (dividers, subtle outlines)
   - Status: --color-status-sold (sold/gifted badges on postscript page)

   ## Typography
   - --font-serif: Headlines (h1-h6), nav links, category filters, artwork links, section links
   - --font-sans: Body text, action buttons (.btn), form controls, metadata
   - Weight 300-400 for most text; 500 only for emphasis (active states, counts)
   - Letter-spacing scale: 0.02em (body) → 0.05em (labels) → 0.1em (nav/titles) → 0.15em (page titles) → 0.2em (uppercase labels)

   ## Spacing Tokens
   - --spacing-xs  (0.5rem /  8px): Tight gaps, small padding
   - --spacing-sm  (1rem   / 16px): Standard inner padding, small gaps
   - --spacing-md  (2rem   / 32px): Section inner padding, standard gaps
   - --spacing-lg  (4rem   / 64px): Large section margins, generous gaps
   - --spacing-2xl (5rem   / 80px): Page title bottom margins, major section breaks
   - --spacing-xl  (8rem   / 128px): Hero/full-page section padding

   ## Buttons
   - Action buttons (.btn): --font-sans, solid bg or outline
   - Navigation/link buttons (.artwork-link, .category-filter__btn, .section-link): --font-serif, elegant style

   ## Transitions
   - Standard: 0.3s ease (links, colors, opacity)
   - Images: 0.5-0.6s ease (scale transforms)
   - Overlays: 0.3-0.4s ease (fade in/out)
