## Visual thesis

Light, left-aligned type-led product story with soft geometry and image-led proof.

CarSignal — Auto Shop Management Software opens with “The AI operating system for auto shops.” in a left-aligned type-led hero. The homepage continues through 14 observed sections, moving from the opening proposition into Your whole floor, on one board, Every handoff stays connected, Meet the AI workforce.

## Color

Light surfaces use 8 repeated semantic colors; the primary action carries the strongest interactive emphasis.

| Token | Value | Role | Usage |
| --- | --- | --- | --- |
| Canvas | `#ffffff` | Page canvas | Dominant rendered page background. |
| Surface 1 | `#fafafa` | Surface | Repeated container or section fill; relative occurrence score 187. |
| Surface 2 | `#1a1816` | Surface | Repeated container or section fill; relative occurrence score 183. |
| Surface 3 | `rgba(255, 255, 255, 0.961)` | Surface | Repeated container or section fill; relative occurrence score 11. |
| Primary text | `#1a1816` | Primary text | Observed display foreground with 17.7:1 contrast against the captured canvas. |
| Secondary text | `#6b6760` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 5.6:1. |
| Action | `#1a1816` | Primary action | Fill used by the dominant first-viewport action. |
| Border | `#a5aab4` | Border and divider | Most repeated inspectable border color. |

## Typography

A single-family system uses Inter across display and reading roles, differentiated by size and weight.

| Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| display | Inter | 61px | 650 | 62.22px | -2.745px | normal | "cv02", "cv03", "cv04", "cv11" | rgb(26, 24, 22) |
| heading | Inter | 50px | 400 | 51px | -2px | normal | "cv02", "cv03", "cv04", "cv11" | rgb(255, 255, 255) |
| body | Inter | 14.5px | 400 | 23.2px | -0.16px | normal | "cv02", "cv03", "cv04", "cv11" | rgb(107, 103, 96) |
| body-small | Inter | 14px | 400 | 21.7px | -0.16px | normal | "cv02", "cv03", "cv04", "cv11" | rgb(107, 103, 96) |
| label | Inter | 10px | 700 | 15.5px | 1.3px | normal | "cv02", "cv03", "cv04", "cv11" | rgb(160, 156, 150) |

## Imagery

Image led media acts as the page’s primary visual proof rather than decoration. A focused visual anchors the first viewport.

- Inventory: 6 images/canvas elements and 0 videos across the analyzed homepage.
- Treatment: fill fitting · square-edged frames

## Motion

12 declared keyframes and 33 active animations were inspectable at capture; observed timing uses 0.65s, 0.2s, 2s.

- Libraries: CSS / browser-native or bundled source not identifiable
- Durations: `0.65s`, `0.2s`, `2s`, `0.4s`, `0.15s`
- Easings: `ease`, `cubic-bezier(0.22, 1, 0.36, 1)`, `ease-out`, `linear`, `ease-in-out`
- Interaction states: transition-all, hover, focus, active, disabled
- Reduced-motion declaration found: yes

## Responsive behavior

Measured at 390 × 844.

- Desktop navigation reduces from 6 visible actions to 3.
- Hero alignment changes from left to center; mobile heading size is 34px.
- 3 multi-column content regions remain on mobile.
- Horizontal overflow: not detected

## Do

- Pair the observed #ffffff canvas with #1a1816 primary copy before adding secondary surfaces.
- Use Inter at 61px/62.22px, weight 650, for the primary display moment.
- Reserve the strongest first-viewport contrast for “Book a demo” within the left-aligned type-led hero.
- Image led media acts as the page’s primary visual proof rather than decoration.

## Don’t

- Do not mix in arbitrary radii; 6px is the repeated treatment on containers.
- Do not reuse the #1a1816 action color across decorative elements; keep its interactive emphasis selective.
- Do not introduce extra type families beyond Inter.
- Do not copy transition-all declarations; keep only purposeful transform or opacity motion.

## Evidence
