# Stratify — Machine Tool Equipment Style Reference
> A precise B2B machine-tool evaluation system with a complete local project brief and RFQ flow.

**Theme:** light

Stratify combines a white technical canvas, a decisive cobalt action color, and slate process bands to make complex equipment easier to evaluate for a project. The system uses compact labels, large editorial headings, plain-language capability summaries, and a three-step qualification journey. Every interactive state supports keyboard access, narrow screens, and local-only RFQ preparation without sending company or project data.

## Tokens — Colors

| Name | Value | Token | Role |
|------|-------|-------|------|
| Canvas | `#f4f7fb` | `--canvas` | Quiet page background behind white product surfaces |
| Paper | `#ffffff` | `--paper` | Header, cards, drawer, form, and readable foreground panels |
| Cobalt | `#0754d9` | `--blue` | Primary buttons, focus rings, labels, and selected states |
| Cobalt Dark | `#053ea3` | `--blue-dark` | Hover and pressed state for the primary action |
| Industrial Slate | `#2e3c54` | `--slate` | Process band, brief count, and technical hero panel |
| Deep Ink | `#17253d` | `--ink` | Main text and footer background |
| Steel Muted | `#617089` | `--muted` | Secondary copy and supporting specifications |
| Divider | `#ccd6e5` | `--line` | Borders, field outlines, and table rules |
| Success | `#087a55` | `--success` | Completed local RFQ confirmation |
| Danger | `#b42318` | `--danger` | Invalid field and blocked action feedback |

## Tokens — Typography

Use Inter as the shared display and body family. The hierarchy relies on weight, scale, and compact tracking instead of ornamental type: large headlines are dense and direct, while product detail remains comfortable at 16px.

### Type Scale

| Role | Family | Weight | Size | Line Height | Letter Spacing | Token |
|------|--------|--------|------|-------------|----------------|-------|
| Caption | Inter | 800 | 12px | 1.3 | 0.13em | `--text-caption` |
| Small body | Inter | 500 | 14px | 1.5 | normal | `--text-body-sm` |
| Body | Inter | 400 | 16px | 1.65 | normal | `--text-body` |
| Card heading | Inter | 750 | 20px | 1.2 | -0.02em | `--text-heading-sm` |
| Section heading | Inter | 760 | 32px | 1.08 | -0.04em | `--text-heading` |
| Display | Inter | 760 | 56px | 1.02 | -0.055em | `--text-display` |

## Tokens — Spacing & Shapes

**Density:** balanced technical procurement

### Spacing Scale

| Name | Value | Token |
|------|-------|-------|
| 1 | 4px | `--space-1` |
| 2 | 8px | `--space-2` |
| 3 | 12px | `--space-3` |
| 4 | 16px | `--space-4` |
| 6 | 24px | `--space-6` |
| 8 | 32px | `--space-8` |
| 12 | 48px | `--space-12` |
| 16 | 64px | `--space-16` |

### Border Radius

| Element | Value | Token |
|---------|-------|-------|
| Controls | 8px | `--radius-control` |
| Cards and panels | 12px | `--radius` |
| Counts and compact labels | 999px | `--radius-pill` |

### Layout

- **Page max-width:** 1180px
- **Desktop gutter:** 24px
- **Mobile gutter:** 16px
- **Hero minimum height:** 640px on wide screens and content-driven on small screens
- **Primary breakpoint:** 760px

## Components

### Header and Mobile Navigation
An 82px sticky white header holds the geometric brand mark, direct section links, and a live project-brief count. Below 760px, navigation becomes a labeled disclosure menu; opening and closing it updates `aria-expanded`, and Escape returns focus to the trigger.

### Editorial Project Hero
A two-column first screen pairs a project-oriented headline with a slate evaluation panel. The panel uses oversized numeric form, restrained rules, and short qualification rows without relying on photography.

### Equipment Capability Cards
Three white cards present a category code, equipment family, application scope, decision criteria, and full-width Add to project brief action. Selection changes the brief state immediately and opens a reviewable RFQ path focused on application fit.

### Qualification Process Band
A slate full-width band explains evaluate, shortlist, and prepare in three equal steps. Cobalt-tinted step numbers establish sequence while keeping paragraph contrast high.

### Local Project Brief and RFQ
The right-side drawer begins empty with RFQ preparation disabled. Adding an equipment family reveals its name and project role, then enables a labeled RFQ form. Company, email, and requirement fields validate locally, produce an explicit completion message, and never perform a network submission.

### Footer
A deep-ink footer repeats the demonstration boundary in plain language and keeps only useful navigation, privacy, and local-RFQ notes.

## Do's and Don'ts

### Do
- Keep cobalt for primary decisions, visible focus, and selected states.
- Present one application summary and one clear Add to project brief action per equipment card.
- Disable RFQ preparation until the project brief contains a named equipment family.
- Preserve the full local sequence: shortlist, inspect, validate, confirm, and reset.
- Reflow the product and process grids to one column below 760px.
- Respect reduced-motion preferences and restore focus after every overlay closes.

### Don't
- Don't add transactional controls or unverified commercial terms.
- Don't enable RFQ preparation while the project brief is empty.
- Don't use unlabelled icon-only controls or hide focus outlines.
- Don't add unsupported performance, stock, delivery, rating, or warranty claims.
- Don't introduce decorative gradients, glass effects, or excessive shadows.
- Don't mix more than one display family and one body family.

## Surfaces

| Level | Name | Value | Purpose |
|-------|------|-------|---------|
| 0 | Technical Canvas | `#f4f7fb` | Page background and breathing space |
| 1 | Paper Surface | `#ffffff` | Equipment cards, navigation, brief, and form |
| 2 | Slate Process | `#2e3c54` | Hero data panel and qualification-process band |
| 3 | Deep Ink Footer | `#17253d` | Closing navigation and legal boundary |

## Elevation

Equipment cards are flat by default with a 1px divider. Hover may add `0 18px 50px rgb(23 37 61 / 10%)`; the project-brief drawer uses a stronger horizontal shadow to separate it from the backdrop. Buttons remain flat and communicate state through color rather than motion.

## Imagery

Favor licensed close crops of machine controls, spindle housings, metal fixtures, and clean work surfaces under cool neutral light. Maintain 3:2 or 4:3 crops, avoid visible trademarks, and keep any cobalt overlay below 16% opacity. The abstract technical panel is the preferred no-image fallback.

## Layout

The page follows a clear procurement sequence: sticky header, split hero, three-card equipment grid, three-step qualification band, local project-brief drawer, and compact footer. Wide layouts use an 1180px centered shell. At 760px the hero, cards, process steps, and footer stack in DOM order; buttons remain at least 48px high and no horizontal scrolling is permitted.

## Agent Prompt Guide

**Quick Color Reference**
- Background: `#f4f7fb` technical canvas and `#ffffff` cards
- Text: `#17253d` primary and `#617089` secondary
- Border: `#ccd6e5`
- Accent: `#0754d9`; hover `#053ea3`
- Process surface: `#2e3c54`

**Example Component Prompts**
1. Create a three-card B2B equipment grid on a white surface. Each 12px-radius card needs a 12px cobalt category code, 20px equipment-family name, concise application copy, decision criteria, and a 48px full-width Add to project brief button.
2. Create a right-side local project-brief drawer with a dim backdrop. Its empty state disables RFQ preparation; its filled state shows the equipment family, project role, remove control, and enabled RFQ form.
3. Create a slate process band with three numbered steps. Use white headings, pale supporting text, cobalt-tinted numbers, and 1px translucent top rules.
4. Create a compact RFQ form with visible company, email, and requirement labels, 46px fields, inline validation, a local completion message, and no form action or remote request.
