Vimcal — Design System

dark · modern · medium · custom · confidence 90% · deep decode

Vimcal sells speed on a night canvas: Plus Jakarta Sans at 52-56px/400 in white on #0A0A0A, 14-18px supporting text, and white 6px-radius buttons. Keyboard-shortcut chips and command-palette UI are the recurring motif — 'the fastest calendar' argued through an interface that looks like it's already responding before you finish the keystroke.

# Vimcal — Design System

> dark, modern, medium, custom — deep decode (measured live)

Vimcal sells speed on a night canvas: Plus Jakarta Sans at 52-56px/400 in white on #0A0A0A, 14-18px supporting text, and white 6px-radius buttons. Keyboard-shortcut chips and command-palette UI are the recurring motif — 'the fastest calendar' argued through an interface that looks like it's already responding before you finish the keystroke.

## Colors

| Role | Value |
|------|-------|
| bg | `#0A0A0A` |
| surface | `#171717` |
| border | `#2B2B2C` |
| text | `#ECECEE` |
| text_muted | `#969697` |
| primary | `#040126` |
| accent | `#FFFFFF` |
| link | `#475467` |
| secondary | `#30356D` |
| button_bg | `#FFFFFF` |
| button_text | `#040126` |

**Using these colors**

- **Action color** `#FFFFFF` — 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 `#FFFFFF` — one role, not several (your action color).
- **accent** `#FFFFFF` — 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** `#040126` — a brand color — but the call-to-action uses #FFFFFF, not this.
- **link** `#475467` — fails contrast on the background (~2.6:1) — this is a dark UI color, NOT a readable link; use the text or action color for links (verify against the reference).
- **secondary** `#30356D` — 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): `#07060A` 68.9% · `#1F0726` 16.2% · `#4C1E45` 9% · `#91829F` 5.9%

## Typography

- Heading: **Manrope**
- Body: **Plus Jakarta Sans**
- Mono: **Geist Mono** _(measured)_

| Role | Size / weight · line-height · tracking |
|------|------------------------------------------|
| hero | 52px / 400 · lh 62px · tracking -1.56px |
| h2 | 46px / 400 · lh 51px · tracking -1.38px |
| h3 | 43px / 400 · lh 48px · tracking -1.3px |
| body | 18px / 400 · lh 29px |
| small | 16px / 500 · lh 19px |

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

> **Fonts —** Manrope — free, on Google. Plus Jakarta Sans — free, on Google.

## Spacing
- base unit: 8px (inferred from the measured scale)
- measured scale: 2px, 8px, 12px, 14px, 16px, 24px, 32px, 40px, 64px, 115px — snap all gaps/padding to these

## Radius
- base: 16px
- button: 6px
- card: 6px
- pill: 9999px
- sharp: 1px

## Buttons

| Button | Fill / text | Border | Radius | Padding | Font | Shadow |
|--------|-------------|--------|--------|---------|------|--------|
| primary | `#FFFFFF` / `#040126` | 1px solid rgb(255, 255, 255) | 6.4px | 9.6px 17.6px 9.6px 17.6px | 500 16px | none |

**States (measured, not guessed)**

- primary focus: outline `1px auto rgb(16, 16, 16)`
- transition: `all 0.3s ease`

## Motion
- durations: 300ms (dominant) · 450ms
- easings: `ease` (dominant)
- animated properties: opacity

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

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

## Layout (measured)
- common grid: 2-col
- nav: 64px fixed · backdrop blur(16px) · border-bottom 1px solid rgba(255, 255, 255, 0.1)

| Section (y) | Height | Cols | Gap | Pad y | Split |
|---|---|---|---|---|---|
| 0 | 900 | 2 | — | 0/0 | — |
| 900 | 254 | — | — | 0/0 | — |
| 1154 | 1249 | — | — | 0/0 | — |

## Motion choreography (measured)
Load order: `div.v-navbar_component` @0ms
- scroll reveal: 3 elements rest at opacity 0, translateY(51px) (3 revealed during the drive).

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

## Responsive (measured)
- breakpoints: 479px · 768px · 991px
- mobile (390px): body 11px · nav: hamburger

## 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.
