Mistral：把大模型写成南法日落

---
version: alpha
name: Mistral-AI-design-analysis
description: Mistral AI brands itself with a singular signature — atmospheric sunset gradients (mustard, orange, deep red) layered over photography of mountains, plus a horizontal "sunset stripe" bar that closes every page. The system pairs warm cream-yellow surfaces ({colors.cream}) with a saturated orange primary CTA ({colors.primary}) and uses an elegant near-serif voice for hero displays. Coverage spans homepage (Frontier AI hero), Le Studio product page, Coding solutions, news article surfaces, contact form, and services tier page — all anchored by the signature gradient closing band.

## Overview

Mistral AI carries itself with a singular, almost cinematographic visual signature — the homepage opens with "Frontier AI. In your hands." rendered in elegant near-serif display type over a photographic mountain landscape bathed in mustard-orange sunset light. Below the hero, every page closes with the same recognizable element: a horizontal "sunset stripe" gradient band running red→orange→yellow→cream that wraps the foot of the page just above the footer. This stripe is THE brand recognizer — it appears on the homepage, products/studio, solutions/coding, news articles, contact form, and services tier page without exception.

The system pairs PP Editorial Old (a near-serif elegant display face) for hero displays with Inter for everything else (body, headings, UI). Cream-yellow surfaces ({colors.cream}, {colors.surface-cream-soft}) anchor form panels and feature cards; saturated orange ({colors.primary}) carries primary CTAs; the deep mountain photography on the homepage and the dark code mockups inside Le Studio create photographic depth. Cards are rectangular with `{rounded.lg}` (12px) corners — distinctly less playful than Miro's or Mintlify's pill-buttons-everywhere approach. Buttons are also `{rounded.md}` (8px), not pills — Mistral's geometry is more sober and editorial than its peers.

**Key Characteristics:**

- Atmospheric mountain-sunset hero photography (orange-red-yellow gradient sky)
- Horizontal "sunset stripe" band ({colors.primary} → {colors.sunshine-700} → {colors.yellow-saturated} → {colors.cream}) at every page bottom
- Cream-yellow surfaces ({colors.cream}, {colors.cream-soft}) for form panels and feature cards
- PP Editorial Old (or similar near-serif) for hero displays; Inter for everything else
- `{rounded.md}` (8px) buttons and `{rounded.lg}` (12px) cards — less playful, more editorial geometry
- Saturated orange primary CTA ({colors.primary}) carries every action call

### Principles

- **Editorial / sans pairing** — PP Editorial Old (near-serif, classical) anchors hero displays; Inter (geometric sans) carries everything else. The contrast IS the brand voice.
- **Generous body leading** (1.55 on body-md) for editorial readability across long-form pages
- **Tight hero leading** (1.05 on 84px display) creates magazine-grade typographic display
- **Negative letter-spacing** progresses with size — display sizes use -1.5px to -0.5px; smaller heads relax to 0
- **Stat-display token** (56px Editorial) for marketing stat callouts ("75% / 80% / 100%")

## Layout

### Spacing System

- **Base unit**: 4px (8px primary increment)
- **Tokens**: `{spacing.xxs}` (4px) · `{spacing.xs}` (8px) · `{spacing.sm}` (12px) · `{spacing.md}` (16px) · `{spacing.lg}` (20px) · `{spacing.xl}` (24px) · `{spacing.xxl}` (32px) · `{spacing.xxxl}` (40px) · `{spacing.section-sm}` (48px) · `{spacing.section}` (64px) · `{spacing.section-lg}` (96px) · `{spacing.hero}` (120px)
- **Section rhythm**: Marketing pages use `{spacing.section-lg}` (96px); content pages tighten to `{spacing.section}` (64px)
- **Card internal padding**: `{spacing.xl}` (24px) for compact cards; `{spacing.xxl}` (32px) for feature panels and form panels

### Grid & Container

- Marketing pages use 1280px max-width with 32px gutters
- Hero band uses 2-column split (text left, sunset photography right) on desktop
- Le Studio product page uses 3-up feature grid below the hero
- Contact page uses 1-column layout with cream form panel centered (~520px max-width)
- Services page uses 4-tier card layout with cream feature panel separator strip

### Whitespace Philosophy

Marketing surfaces give content generous breathing room — `{spacing.hero}` (120px) hero padding lets the mountain-sunset photography fill the frame. Form pages tighten dramatically: contact form panel uses `{spacing.xxl}` (32px) internal padding, fields stack on `{spacing.md}` (16px) gap.

## Elevation & Depth

The system runs predominantly flat with strategic atmospheric depth from photography.

| Level      | Treatment                                  | Use                                    |
| ---------- | ------------------------------------------ | -------------------------------------- |
| 0 (flat)   | No shadow; `{colors.hairline-soft}` border | Default cards, table rows, form inputs |
| 1 (subtle) | `rgba(0, 0, 0, 0.04) 0px 1px 2px 0px`      | Hover-elevated tiles                   |
| 2 (card)   | `rgba(0, 0, 0, 0.04) 0px 4px 12px 0px`     | Standard feature cards                 |
| 3 (mockup) | `rgba(0, 0, 0, 0.08) 0px 12px 24px -4px`   | IDE mockup, code editor frames         |
| 4 (modal)  | `rgba(0, 0, 0, 0.12) 0px 16px 48px -8px`   | Modals, dropdowns                      |

### Decorative Depth

- The atmospheric depth on Mistral's hero comes from the photographic mountain-sunset imagery — natural light gradient does the work
- The "sunset stripe" closing band carries depth via its multi-stop gradient (red → orange → yellow → cream)
- IDE / code mockups use dark-canvas backgrounds with subtle drop shadow

## Shapes

### Border Radius Scale

| Token            | Value  | Use                                                                    |
| ---------------- | ------ | ---------------------------------------------------------------------- |
| `{rounded.xs}`   | 4px    | Small chips, micro-controls                                            |
| `{rounded.sm}`   | 6px    | Discount badges, compact UI                                            |
| `{rounded.md}`   | 8px    | Buttons, inputs, search-pill, code blocks                              |
| `{rounded.lg}`   | 12px   | Cards, modals, panels (the dominant card radius)                       |
| `{rounded.xl}`   | 16px   | Larger feature panels                                                  |
| `{rounded.xxl}`  | 20px   | Featured emphasis cards                                                |
| `{rounded.full}` | 9999px | Status badges, pill tabs (used sparingly — most buttons are NOT pills) |

The radius scale is sober and editorial — Mistral does NOT use pill buttons. `{rounded.md}` (8px) for buttons, `{rounded.lg}` (12px) for cards, `{rounded.full}` reserved for badges and the rare pill tab.

### Photography Geometry

- Hero photography is full-bleed atmospheric mountain-sunset imagery with no internal framing
- IDE/code mockups render with `{rounded.lg}` (12px) corners on dark canvas
- Customer logos wall presents wordmarks inline at consistent 60–80px height
- Product imagery (Le Studio mockup, agent UI mockups) sits in `{rounded.lg}` panels with subtle border

## Do's and Don'ts

### Do

- Reserve `{colors.primary}` (saturated orange) for primary CTAs and active states only
- Use the **sunset stripe band** at the foot of every page — it's the brand's most recognizable signature
- Pair PP Editorial Old (display) with Inter (UI) — never substitute either with a generic alternative
- Apply `{rounded.md}` (8px) to buttons and `{rounded.lg}` (12px) to cards consistently
- Use cream-yellow surfaces ({colors.cream}) for form panels, feature cards, and footer
- Anchor heroes with photographic mountain-sunset imagery (or its visual equivalent — atmospheric gradient sky)
- Use stat-display token (PP Editorial 56px) for stat callouts to maintain editorial character

### Don't

- Don't use pill-shaped buttons (`{rounded.full}`) — Mistral's geometry is sober and editorial, not playful
- Don't introduce additional accent colors beyond the orange/yellow/cream sunset palette
- Don't reduce hero leading below 1.05 — the editorial display needs that magazine-grade tightness
- Don't replace PP Editorial Old hero displays with Inter — the editorial / sans contrast IS the brand
- Don't apply heavy shadows on flat documentation cards; reserve elevation for IDE mockups
- Don't drop the sunset stripe band from any page bottom — it's the brand's continuity element

## Responsive Behavior

### Breakpoints

| Name           | Width         | Key Changes                                                                                                   |
| -------------- | ------------- | ------------------------------------------------------------------------------------------------------------- |
| Mobile (small) | < 480px       | Single column. Hero scales to 40px (PP Editorial). Pill nav collapses to hamburger. Pricing tiers stack 1-up. |
| Mobile (large) | 480 – 767px   | Feature tiles 2-up. Hero scales to 52px.                                                                      |
| Tablet         | 768 – 1023px  | 2-column feature grids. Pill-tab nav returns. Hero 64px.                                                      |
| Desktop        | 1024 – 1279px | Multi-column layouts. Hero 76px. Stat row at full width.                                                      |
| Wide Desktop   | ≥ 1280px      | Full 84px hero presentation.                                                                                  |

### Touch Targets

- Buttons render at 40–44px effective height — at WCAG AAA floor with `10px 20px` padding
- Form inputs render at 44px height
- Pill tabs render at ~32px tall — bumps to 44px on mobile

### Collapsing Strategy

- **Promo banner** stays full-width; truncates at < 480px
- **Top nav** below 1024px collapses to hamburger
- **Hero band**: 2-column hero (text + photography) collapses to stacked at < 1024px
- **Pricing tiers**: 4-column desktop → 2-column tablet → 1-column mobile
- **Stat row**: 3-column → stacked at < 768px
- **Hero typography**: 84px → 64px → 52px → 40px
- **Footer**: 5-column desktop → 3-column tablet → 1-column accordion mobile
- **Sunset stripe band** stays full-width on all breakpoints

### Image Behavior

- Mountain-sunset photography uses 16:9 ratio with full-bleed scaling
- IDE mockup images maintain aspect ratio across breakpoints
- Customer logo wall presents wordmarks at consistent 60–80px height

## Iteration Guide

1. Focus on ONE component at a time
2. Reference component names and tokens directly (`{colors.primary}`, `{component-name}-pressed`)
3. Run `npx @google/design.md lint DESIGN.md` after edits
4. Add new variants as separate `components:` entries
5. Default to `{typography.body-md}` for body and `{typography.subtitle}` for emphasis. Hero displays use `{typography.hero-display}` (PP Editorial Old).
6. Keep `{colors.primary}` confined to primary CTAs, active states, and the sunset stripe band
7. Cards use `{rounded.lg}` (12px), buttons use `{rounded.md}` (8px). Pills (`{rounded.full}`) reserved for badges only.
8. Always include the sunset-stripe-band component at the foot of every page mockup.

## Known Gaps

- Specific dark-mode token values not surfaced; the brand has not shipped a published dark-mode palette
- Animation/transition timings not extracted; recommend 150–200ms ease for hover/focus state transitions
- Form validation success state not explicitly captured beyond defaults
- Sunset stripe band gradient stops are approximations — the actual values may vary slightly across pages but the visual rhythm is consistent
