## Visual thesis

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

Magma opens with “Monetize your agent’s mistakes.” in a left-aligned stacked hero. The homepage continues through 11 observed sections, moving from the opening proposition into Logs. Interactions. Mistakes, What sits under your agent, How it works.

## Color

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

| Token | Value | Role | Usage |
| --- | --- | --- | --- |
| Canvas | `#e8ebe7` | Page canvas | Dominant rendered page background. |
| Surface 1 | `#22302b` | Surface | Repeated container or section fill; relative occurrence score 30. |
| Surface 2 | `#f3f5f1` | Surface | Repeated container or section fill; relative occurrence score 30. |
| Surface 3 | `#ffffff` | Surface | Repeated container or section fill; relative occurrence score 7. |
| Primary text | `#17201c` | Primary text | Observed display foreground with 13.9:1 contrast against the captured canvas. |
| Secondary text | `#47544d` | Secondary text | Observed reading foreground; measured canvas-reference contrast is 6.6:1. |
| Action | `#17201c` | Primary action | Foreground used by the dominant first-viewport action. |
| Border | `#cfd6d0` | Border and divider | Most repeated inspectable border color. |

## Typography

The observed type system assigns Instrument Serif to display, heading text; Newsreader to body, label text.

| Role | Family | Size | Weight | Line height | Tracking | Style | Features | Color |
| --- | --- | --- | --- | --- | --- | --- | --- | --- |
| display | Instrument Serif | 84px | 400 | 82.32px | -1.848px | normal | none | rgb(23, 32, 28) |
| heading | Instrument Serif | 76px | 400 | normal | 0px | normal | none | rgb(23, 32, 28) |
| body | Newsreader | 20px | 300 | 32.4px | 0px | normal | none | rgb(71, 84, 77) |
| label | Newsreader | 15px | 400 | normal | 0px | normal | none | rgb(255, 255, 255) |

## Spacing and shape

- Base unit: 4px
- Density: sparse
- Maximum content width: 1440px
- Section gap: 56px
- Container padding: 24px
- Common spacing: `12px`, `24px`, `26px`, `4px`, `20px`, `22px`, `18px`, `56px`, `9px`, `16px`
- Corner strategy: Soft geometry is the dominant shape voice. Separation relies on borders and surface contrast rather than shadow.
- Radii: Pills `50px`, Cards `14px`, Containers `8px`, Media `0px`, Buttons `0px`
- Borders: `1px solid rgb(207, 214, 208)`, `1px solid rgb(220, 226, 220)`, `1px solid rgb(228, 233, 227)`
- Shadows: `None observed`

## Layout

- Macrostructure: Stacked product narrative
- Hero: Stacked hero: message leads into visual proof within the opening
- Grid: 2 columns
- Footer: Closing link index with 3 actions
- Reading flow: The homepage continues through 11 observed sections, moving from the opening proposition into Logs. Interactions. Mistakes, What sits under your agent, How it works.
- Section sequence: Logs. Interactions. Mistakes. → What sits under your agent. → How it works. → Tell us → Onboard → Earn → See what it earns. → Buying? → Frequently asked questions. → Magmatize your data. → Magma.

## Component grammar

### Hero

Stacked, left-aligned opening anchored by “Magmatize your data →”.

- Role: Opening proposition
- Observed instances: 1
  - Pattern: `stacked`
  - Alignment: `left`
  - Heading: `Instrument Serif · 84px / 400`
  - Media: `image-led`

### Navigation

Static navigation with 4 visible actions in the desktop opening.

- Role: Global wayfinding
- Observed instances: 1
  - Text: `#17201c`
  - Border: `none`
  - Radius: `0px`
  - Padding: `0px 0px 0px 0px`
  - Type: `Newsreader · 17px / 400`
  - Position: `static`
  - Height: `42px`

### Primary action

“Magmatize your data →” is the strongest first-viewport action by semantic intent and visual contrast.

- Role: Conversion
- Observed instances: 1
  - Text: `#17201c`
  - Border: `none`
  - Radius: `0px`
  - Padding: `0px 0px 8px 0px`
  - Type: `Newsreader · 19px / 400`

3 style-matched content card instances were found among 3 candidates; properties describe the dominant observed cluster.

- Role: Repeated content module
- Observed instances: 3
  - Text: `#17201c`
  - Border: `none`
  - Radius: `14px`
  - Padding: `0px 0px 0px 0px`
  - Type: `Newsreader · 16px / 400`
  - Candidate pool: `3`

### Badge or tag

  - Type: `Newsreader · 16px / 400`
  - Candidate pool: `2`

### Media frame

2 style-matched media elements were found among 6 rendered candidates; fill fitting and 0px are the most repeated treatments.

- Role: Visual proof
- Observed instances: 2
  - Fit: `fill, cover`
  - Ratios: `1.00, 2.69, 2.09, 1.28, 2.49`
  - Radius: `0px`

## Imagery

Image led media acts as the page’s primary visual proof rather than decoration. Multiple visual elements share the first viewport.

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

## Motion

5 declared keyframes and 0 active animations were inspectable at capture; observed timing uses 0.18s.

- Libraries: CSS / browser-native or bundled source not identifiable
- Durations: `0.18s`
- Easings: `ease`, `ease, ease`
- Interaction states: hover, focus, disabled, active
- Reduced-motion declaration found: yes

## Responsive behavior

Measured at 390 × 844.

- Desktop navigation reduces from 4 visible actions to 3.
- Hero alignment changes from left to center; mobile heading size is 44.85px.
- 1 multi-column content region remains on mobile.
- Horizontal overflow: not detected

## Do

- Pair the observed #e8ebe7 canvas with #17201c primary copy before adding secondary surfaces.
- Use Instrument Serif at 84px/82.32px, weight 400, for the primary display moment.
- Reserve the strongest first-viewport contrast for “Magmatize your data →” within the left-aligned stacked hero.
- Image led media acts as the page’s primary visual proof rather than decoration.

## Don’t

- Do not mix in arbitrary radii; 50px is the repeated treatment on pills.
- Do not reuse the #17201c action color across decorative elements; keep its interactive emphasis selective.
- Do not introduce extra type families beyond Instrument Serif and Newsreader.
- Do not add card shadows; the source separates content without repeated elevation.

## Evidence

- Hero: `/captures/magma/hero.webp` (960 × 600, scroll 0px) — Visible section: Monetize your agent’s mistakes. · Logs. Interactions. Mistakes.
- Mid-page: `/captures/magma/middle.webp` (960 × 600, scroll 2273px) — Visible section: Buying? · Frequently asked questions.
- Closing: `/captures/magma/closing.webp` (960 × 600, scroll 4325px) — Closing viewport evidence
- Mobile: `/captures/magma/mobile.webp` (390 × 844, scroll 0px) — Visible section: Monetize your agent’s logs.

## Confidence notes

- The hero heading was read from semantic heading markup.
- 5 responsive breakpoint declarations were inspectable.
- 3 stylesheets were inspectable; 0 cross-origin stylesheets were unavailable to rule inspection.
- Computed styles describe the captured render; source design tokens and proprietary font files were not copied.
