    "overview": "Greenhouse Catalogue is for online shops that should read like a printed magazine. Product pages are stories, collection pages are spreads, and checkout is the quiet last page. Hierarchy comes from a 64px display headline against 16px body text, wide margins and one green action color (primary). Every other surface is warm paper and ink, so photography and copy carry the page.",
    "color": "Neutrals are warm paper to ink (hue ~45, low chroma). neutral.50 #faf8f3 is the page and neutral.950 #181714 is the text, so nothing renders as cool grey. Brand green (hue ~150) is the only chromatic accent. Use it for primary, ring, links and accent fills. Success is a bluer teal (hue ~170) so confirmations never read as a call to action. Destructive is a crimson (hue ~345), far from green in both modes. The warning ramp was re-curved so chroma rises smoothly to 400–500 instead of jumping, which removes the muddy 300 step. Light contrast: primary-foreground on primary is 5.1:1, destructive-foreground on destructive 5.6:1, muted-foreground on muted 6.6:1, and primary on background 4.8:1. Dark contrast: primary-foreground on primary is 6.7:1, destructive 6.3:1, warning 6.9:1, and muted-foreground on muted 6.2:1.",
    "typography": "The scale is a major third (1.25) from a 16px base, rounded to the 4px grid: 16, 20, 24, 32, 48, 64. The 39px step is skipped on purpose, so the display sizes jump hard like a masthead. 18px (body-lg) is a half-step for lead paragraphs. Sora (600/700) is used only at 32px and above: display-lg, display-md and heading-lg. Its tracking tightens from -0.02em at 32px to -0.035em at 64px. Plus Jakarta Sans (400–700) sets heading-md and below, body, labels, forms and prices. Body line heights land on the grid: 16/26, 18/28 and 14/22. JetBrains Mono (400/500) is only for SKUs, order numbers and codes.",
    "layout": "Spacious density on a 4px grid. Section gaps are {space.16}–{space.24} (64–96px), and card padding is {space.8} (32px). Use a 12-column grid with a 1200px max content width. Long-form editorial copy sits in a 640px column. Hero headlines leave one empty column beside them.",
    "elevation": "Print is flat, so the system is too. Cards separate from the page with a 1px border and whitespace. Their shadow.sm is a 5% ink tint and is barely visible. shadow.md is for menus and popovers. shadow.lg is for dialogs and the sticky cart drawer. In dark mode, depth comes from surface steps rather than shadows: background #181714, card #211f1b, then popover and muted at neutral.900 and neutral.800.",
    "shapes": "Radii are small, like trimmed paper: {radius.md} 4px on buttons and inputs, {radius.lg} 6px on cards. {radius.full} is only for badges and avatars. Product imagery is never rounded beyond 6px."
