Reference screenshots live beside this file; look at them before writing any layout, they carry the composition, density and image treatment that tokens cannot:

- `screenshots/desktop-1440-fold.png`: Desktop 1440, above the fold
- `screenshots/desktop-1440-full.jpg`: Desktop 1440, full page
- `screenshots/laptop-1024-fold.png`: Laptop 1024, above the fold

- `screenshots/phone-390-fold.png`: Phone 390, above the fold

## Responsive Behavior

| Viewport | Content width | Gutter | Body | H1 | Header | Hero | Grids | Buttons |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| desktop 1440px | 1420px | 1124px | 16px | 24px, 1 line, right | 0px, 2 links | media behind/overlapping text | 2→1 col; 4→4 col; 2→1 col | content-width |
| laptop 1024px | 1004px | 708px | 16px | 24px, 1 line, right | 0px, 2 links | media behind/overlapping text | 2→1 col; 4→4 col; 2→1 col | content-width |
| tablet 768px | 748px | 452px | 16px | 24px, 1 line, right | 0px, hamburger (Open main menu) | media behind/overlapping text | 2→1 col; 4→4 col; 2→1 col | content-width |
| phone 390px | 370px | 42px | 16px | 24px, 2 lines, left | 0px, hamburger (Open main menu) | text only | 4→4 col; 2→1 col; 2→1 col | 3 full-width |

- H1 goes 24px → 24px (100%), 1 → 2 lines.
- Nav collapses to a hamburger by 390px (first seen at 768px); header 0px → 0px.
- Hero: media behind/overlapping text → text only.
- Card grids: 4 columns → 4 columns on phones (gap 10px → normal).
- Body text stays 16px at every width.
- Phone side gutter 42px.
- 3 buttons stretch full-width on phones.

## Interaction & Motion

118 elements carry transitions; typical 0.2s with cubic-bezier(0.37, 0, 0.63, 1), mostly on opacity, color, background-color. No running keyframe animations at rest.

- Hover on button-primary ("SHOP MEN"): no visible change; cursor pointer; transition background-color, color, border-color, opacity | 0.2s, 0.2s, 0.2s, 0.2s | cubic-bezier(0.37, 0, 0.63, 1), cubic-bezier(0.37, 0, 0.63, 1), cubic-bezier(0.37, 0, 0.63, 1), cubic-bezier(0.61, 1, 0.88, 1) | delay 0s, 0s, 0s, 0s.
- Hover on button-secondary ("SHOP WOMEN"): no visible change; cursor pointer; transition background-color, color, border-color, opacity | 0.2s, 0.2s, 0.2s, 0.2s | cubic-bezier(0.37, 0, 0.63, 1), cubic-bezier(0.37, 0, 0.63, 1), cubic-bezier(0.37, 0, 0.63, 1), cubic-bezier(0.61, 1, 0.88, 1) | delay 0s, 0s, 0s, 0s.
- Hover on nav-link ("New Arrivals"): no visible change; cursor pointer; transition opacity | 0.2s | cubic-bezier(0.37, 0, 0.63, 1).
- Focus on button-primary: element did not take focus.
- Tooltip triggers exist (21 × title) but none opened on hover in the first viewport; title attributes fall back to the browser's native tooltip.
- No dropdown menus found in the header.
- 24 sizable elements sit at opacity 0 before scrolling: scroll-reveal animations are in use (reveal on enter, fade + rise is the usual recipe).

Full detail (every overlay, table, form, scroll and text rule measured) is in `BEHAVIOR.md`; raw evidence in `evidence.json`.

## Do's and Don'ts

- Do use 4px multiples for every padding, margin and gap; the site does not use odd values.
- Do reserve `#212121` for actions and focus; never paint large areas with it.
- Do keep body text at 14px in Geograph.
- Do match corner radii per element class (buttons 9999px, cards 0px); do not pick one radius for everything.
- Do use the measured shadows above; do not invent heavier ones.
- Don't substitute a different accent hue or introduce gradients that are not listed above.
- Don't rebuild from the tokens alone; open the screenshots for composition, density and image treatment.
- Note: The primary action colour is the ink colour (monochrome palette); chromatic colours appear only as small accents.
- Note: Body text contrast is 1.0:1 against the page background (below 4.5:1).
