- **Section vertical gaps:** clamp(4rem, 8vw, 8rem).
- **Hero layout:** Split-screen (text left, visual right).
- **Feature sections:** Zig-zag alternating text+image rows. No 3-equal-columns.
- **Mobile collapse:** All multi-column layouts collapse below 768px. No horizontal overflow.
- **z-index contract:** base (0) / sticky-nav (100) / overlay (200) / modal (300) / toast (500).

## Elevation & Depth

Strict 3x3 CSS grid layout, uniform gap spacing (16px), subtle hover scale (1.02) on grid items, clean thin borders between cells, smooth fade-in on scroll for each cell, minimal shadow on hover

- **Physics:** Ease-out curves, 200-300ms duration. Smooth and predictable.
- **Entry animations:** Fade + translate-Y (16px → 0) over 420ms ease-out. Staggered cascades for lists: 80ms between items.
- **Hover states:** Subtle color shift + shadow adjustment over 200ms.
- **Page transitions:** Fade only (200ms).
- **Performance:** Only transform and opacity animated. No layout-triggering properties.

## Shapes

Base corner radius: 8px. See rounded tokens in front matter for the full scale.

## Components

- **Primary Button:** Rounded (8px) shape. Accent color fill. Hover: 8% darken + subtle lift shadow. Active: -1px translate tactile press. Font weight 600. No outer glows.
- **Secondary / Ghost Button:** Outline variant. 1.5px border in muted color. Text in primary color. Hover: subtle background fill.
- **Cards:** Rounded (8px) corners. Surface background. Subtle shadow (0 2px 12px rgba(0,0,0,0.06)). 1px border stroke.
- **Inputs:** Label above input. 1px border stroke. Focus ring: 2px accent color offset 2px. Error text below in semantic red. No floating labels.
- **Navigation:** Primary surface background. Active item: accent color indicator. Font weight 500 when active.
- **Skeletons:** Shimmer animation matching component dimensions. No circular spinners.
- **Empty States:** Icon-based composition with descriptive text and action button.

- No `h-screen` — use `min-h-[100dvh]`

- No broken external image links — use picsum.photos or inline SVG
- No generic lorem ipsum in demos
