Decoded design system

Sdlc Dev's decoded design system: background #FFFFFF, text #0A0A0A, accent #297BFF, link #737373, primary #2C2A59; type scale h1 48px / h2 36px / body 14px; 4px spacing base; 4px base radius. The single interactive/action color is #297BFF — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Using these colors

• Action color #297BFF — the single interactive color; only on things you click or must notice, never large fills.
• accent, button_bg are all #297BFF — one role, not several (the action color).
• accent #297BFF — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
• primary #2C2A59 — a brand color — but the call-to-action uses #297BFF, not this.
• link #737373 — reads as a neutral UI color, not a link accent — verify against the reference (action = #297BFF).
• secondary #94BDFF — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.

# Sdlc Dev — Design System

> light, professional, medium, tailwind — deep decode (measured live)

## Colors

| Role | Value |
|------|-------|
| bg | `#FFFFFF` |
| surface | `#F0F0F0` |
| border | `#DADADA` |
| text | `#0A0A0A` |
| text_muted | `#676767` |
| primary | `#2C2A59` |
| accent | `#297BFF` |
| link | `#737373` |
| secondary | `#94BDFF` |
| button_bg | `#297BFF` |
| button_text | `#FFFFFF` |

**Using these colors**

- **Action color** `#297BFF` — the single interactive color; it appears only on things you click or must notice (buttons, key highlights), never on large fills or backgrounds.
- `accent`, `button_bg` are all `#297BFF` — one role, not several (your action color).
- **accent** `#297BFF` — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
- **primary** `#2C2A59` — a brand color — but the call-to-action uses #297BFF, not this.
- **link** `#737373` — reads as a neutral UI color, not a link accent — verify against the reference (action = #297BFF).
- **secondary** `#94BDFF` — optional secondary accent — LOW decode confidence; use rarely (a status color or a single decorative moment) or omit it entirely. Prefer one accent unless the reference clearly shows two.
- **Page coverage** (full-page screenshot pixels): `#FFFFFF` 76.1% · `#D8E4F8` 15.1% · `#6F8ECA` 8.8%

## Typography

- Heading: **Geist**
- Body: **Geist**

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 48px / 500 · lh 48px |
| h2 | 36px / 600 · lh 40px |
| h3 | 24px / 500 · lh 32px |
| body | 14px / 400 · lh 20px |
| small | 12px / 300 · lh 16px |

- Weight ladder: 300 · 400 · 500 · 600 — use these exact measured weights, not the 400/600 defaults.

> **Fonts —** Geist — free, on Google.

## Spacing
- base unit: 4px (inferred from the measured scale)
- measured scale: 2px, 4px, 6px, 8px, 10px, 12px, 16px, 18px, 24px, 32px — snap all gaps/padding to these
- section rhythm: 40px top/bottom padding per section (measured)

## Radius
- base: 4px
- button: 3.35544e+07px
- card: 16px
- pill: 9999px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#297BFF` / `#FFFFFF` | 1px solid rgba(204, 204, 204, 0.5) | 3.35544e+07px | 18px 18px 18px 18px | 400 14px | none |
| secondary | `oklab(0.946017 0.0000430942 0.0000189543 / 0.5)` / `#737373` | 1px solid rgba(204, 204, 204, 0.5) | 3.35544e+07px | 6px 6px 6px 10px | 400 14px | none |

**States (measured, not guessed)**

- primary hover: background `#003180`
- primary focus: outline `1px auto rgb(16, 16, 16)`
- secondary hover: background `rgba(209, 209, 209, 0.5)` · color `#171717`

## Motion
- durations: 150ms (dominant)
- easings: `cubic-bezier(0.4, 0, 0.2, 1)` (dominant)
- animated properties: color, background-color, border-color, outline-color

Micro-interactions use the dominant duration + easing; nothing on the page animates slower than the longest duration above — don't invent springier motion.

_…and 104 more measured on the page._

Prefer these names when extending their system — it's the brand's actual vocabulary.

## Layout (measured)
- container max 1400px · common grid: 2-col
- nav: 56px sticky

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 72 | 574 | 2 | — | 0/0 | 57/43 |
| 686 | 654 | 3 | 16 | 32/32 | — |
| 1396 | 226 | — | — | 24/24 | — |
| 1670 | 177 | — | — | 40/40 | — |

## Motion choreography (measured)
- overlay dialog (auto-opened): panel #FAFAFA · r 12px · border 1px solid rgba(204, 204, 204, 0.5) · shadow 
  - enter: transform+opacity from scale(1.06),0 · 300ms linear
  - exit: transform+opacity from scale(1),1 · 300ms linear

Rebuild the timeline, not just the durations — order, delays and staggers above are the choreography.

## Components (measured)
- link: #737373 · no underline — hover #171717

## Themes (both measured)
- dark counterpart: bg `#121212` · text `#EBEBEB`
- tokens that flip between modes:
  - `--references-color`: `#46af65` → `#99ffb7`
  - `--course-color`: `#cc8b00` → `#fff383`
  - `--sdlc-color`: `#ad46ff` → `#d299ff`
  - `--tips-color`: `#e60076` → `#ff99cd`
  - `--project-color`: `#297bff` → `#99e6ff`
  - `--color-fd-secondary`: `#ededed` → `#212121`
  - `--color-landing-foreground`: `#2c2a59` → `#d0dbe4`
  - `--color-fd-border`: `#cccccc80` → `#6663`

## Responsive (measured)
- breakpoints: 448px · 640px · 768px · 1024px · 1280px
- mobile (390px): hero 28px · body 16px · nav: inline

## How to apply
Paste the Tailwind `@theme` (or CSS variables) as your base, then build each
section to its spec — verify every color, radius, and font against these tokens.
Hover/focus states, shadows and motion timings above are measured from the live page — match them exactly, don't re-guess them.
