## Overview

Access Denied

Sharp, squared-off controls, flat surfaces separated by hairlines, restrained display type at 32px / 700, a monochrome palette. The site ships in light mode by default. Measured from 4 rendered elements at 1440px wide on 2026-09-28.

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/tablet-768-fold.png`: Tablet 768, above the fold
- `screenshots/phone-390-fold.png`: Phone 390, above the fold
- `screenshots/phone-390-full.jpg`: Phone 390, full page

- **Times New Roman** for h1, body: system font stack.

| Role | Family | Size | Weight | Line height | Tracking |
| --- | --- | --- | --- | --- | --- |
| headline-display | Times New Roman | 32px | 700 | 1.4 | normal |

| label-md | Times New Roman | 13px | 500 | 1.4 | normal |
| button | Times New Roman | 14px | 500 | 1.4 | normal |

Type scale in use: 16px, 32px. Base body size 16px.

The H1 renders at 32px / 700, start aligned, up to 1424px wide. Sample: "Access Denied".

## Layout

- Spacing unit: 8px. Scale in use: 16, 24 (px).
- Content max width: not detected (fluid).

## Elevation & Depth

No box shadows in use; depth comes from hairline borders and surface tints (flat design).

## Shapes

- Buttons: 0px
- Inputs: 0px
- Cards and panels: 0px
- Images and media: 0px
- Radius scale: none 0px, full 9999px

## Components

## Dark Mode

No dark mode responded to prefers-color-scheme, a theme toggle, or a root class/attribute.

## Responsive Behavior

| Viewport | Content width | Gutter | Body | H1 | Header | Hero | Grids | Buttons |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| desktop 1440px | fluid |  | 16px | 32px, 1 line, start |  | text only |  | content-width |
| laptop 1024px | fluid |  | 16px | 32px, 1 line, start |  | text only |  | content-width |
| tablet 768px | fluid |  | 16px | 32px, 1 line, start |  | text only |  | content-width |
| phone 390px | fluid |  | 16px | 32px, 1 line, start |  | text only |  | content-width |

- H1 goes 32px → 32px (100%), 1 → 1 lines.
- Body text stays 16px at every width.
- Horizontal overflow at 390px (the source has a responsive bug; do not copy it).

## Interaction & Motion

No CSS transitions on rendered elements: state changes are instant.

- No tooltips: nothing on the page carries tooltip attributes or roles and no tooltip styles exist. Do not add tooltips when rebuilding.
- No dropdown menus found in the header.
- No scroll-reveal: content is visible without scrolling into view.

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 8px multiples for every padding, margin and gap; the site does not use odd values.
- Do keep body text at 16px in Times New Roman.
- Do match corner radii per element class (buttons 0px, cards 0px); do not pick one radius for everything.
- Don't add drop shadows; this design is flat.
- 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.
