# Cash Runway (Notchset): prompt.md (v1.0.0)

- id: `cash-runway` · version 1.0.0 · block · pro (Pro)
- category: Data
- build: Base UI (one set of files; its dependencies follow the build)
- install (this build): `npx shadcn@latest add @beautiful-ui-pro/cash-runway`
- npm dependencies: class-variance-authority@^0.7
- registry dependencies: utils, @beautiful-ui/segmented-control, https://beautiful-ui.dev/r/notchset-foundation.json
- docs: https://beautiful-ui.dev/components/cash-runway
- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

A runway planner: runway in rolling months, the cash-out date, net burn and DEFAULT ALIVE / DEAD with break-even; a 36-month cash line that glides between scenarios against the base plan with cash-out, break-even and event markers; plan presets, hires and growth levers that squash while dragged, an inference-model switch; and key events (raise, one-off cost, contract, recurring cost) that move the projection.

## Build it
- Stack: React 19 (`ref` is a plain prop), TypeScript, Tailwind CSS v4 utilities, a shadcn-initialised project with the `@/*` alias.
- Packages: `class-variance-authority@^0.7`.
- Files: `components/ui/notchset/blocks/cash-runway.tsx`; shared code: `lib/beautiful-ui/notchset/instrument.tsx`, `lib/beautiful-ui/notchset/root.ts`, `lib/beautiful-ui/notchset/button-variants.ts`, `lib/beautiful-ui/notchset/field-classes.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `segmented-control`, `notchset-foundation`.
- Builds: one set of files for both, but its dependencies come in Base UI and Radix builds. Install the one that matches the project (see Install): a free item's bare URL installs the Base UI build of it and its dependencies.
- Exports to keep: `CashRunway`, `project`, and every exported type.
- CSS: the install adds the notchset foundation (tokens, keyframes, motion levels) to your global stylesheet once. Nothing to import by hand.
- Re-running `add` (or `--overwrite`) re-applies those rules: put overrides in your own CSS, never in the installed rules.
- Tokens: retheme with the `--notchset-*` custom properties (`--notchset-check`, `--notchset-control-edge`, `--notchset-draw-from`, `--notchset-ease-bloom`, `--notchset-ease-glide`, `--notchset-ease-key-down`, `--notchset-ease-key-up`, `--notchset-ease-travel`, `--notchset-fade`, `--notchset-focus-color`, `--notchset-focus-inset`, `--notchset-grow-to`, `--notchset-key-down`, `--notchset-key-up`, `--notchset-life-from`, `--notchset-life-ms`, `--notchset-node-blink`, `--notchset-node-bloom`, `--notchset-node-delay`, `--notchset-plate-color`, `--notchset-rise-from`, `--notchset-rule`, `--notchset-scan-to`, `--notchset-scroll`, `--notchset-signal`, `--notchset-sweep-to`, `--notchset-travel`). Never add Tailwind colour classes inside the component.

```tsx
import { CashRunway, type RunwayEvent } from "@/components/ui/notchset/blocks/cash-runway";
```

## Parts

| Part | data-slot | What it is for |
|---|---|---|
| `CashRunway` | `cash-runway` | KPIs, the projection chart, key events and levers. |

Style a part with `[data-slot="<slot>"]` selectors or its `className`; keep the attributes when editing.

## Sound
- Keep every `data-slot` and `data-sound` attribute: the sound layer reads them.
- Installing this item adds no audio. Nothing plays until the app mounts `SoundProvider` once (install: `npx shadcn@latest add https://beautiful-ui.dev/r/notchset-sound.json`, import from `@/components/ui/notchset/sound-provider`); `useSound()` gives `muted` and `setMuted` for a mute control. Without a provider the audio engine never loads.

## Match the original
- Read `components/ui/notchset/blocks/cash-runway.tsx` as the reference implementation before changing or recreating anything, and match it: sizes, colours per theme, motion timings, copy and behaviour.
- If you deviate (a prop you can't honour, a style you changed, a dependency you swapped), say so in your reply, part by part.
- Keep the accessibility contract, the keyboard map and the motion levels listed below.

## Use it when
- cash runway, burn rate, default alive, financial model, startup finance, scenario planning, forecast, Notchset
- A founder or finance view of how long the cash lasts
- Trying hiring, growth and cost scenarios side by side with the plan

### Not when
- Accounting-grade forecasts: export to your planning model
- Budget against actual: use Budget Variance

## Mistakes
- Replace the projection with your planning model before showing real numbers
- Keep event units straight: one-time in dollars, recurring in dollars a month

## Usage

```tsx
import { CashRunway, type RunwayEvent } from "@/components/ui/notchset/blocks/cash-runway";

export function Runway({ events }: { events: RunwayEvent[] }) {
  return (
    <CashRunway
      inputs={{ cash: 18_400_000, revenue: 410_000, fixedCost: 1_050_000, hireCost: 18_000 }}
      plans={[{ id: "base", label: "BASE", hires: 4, growth: 6, model: "flash", note: "4 HIRES A QUARTER · 6% GROWTH" }]}
      models={[{ id: "flash", label: "ATLAS 3 FLASH", share: 0.23, note: "INFERENCE IS 23% OF REVENUE" }]}
      start="2026-10"
      defaultEvents={events}
      onEventsChange={(next: RunwayEvent[]) => localStorage.setItem("runway-events", JSON.stringify(next))}
    />
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `inputs` | `{ cash, revenue, fixedCost, hireCost }` |  | Starting cash and monthly revenue and costs, in dollars. |
| `plans` | `{ id, label, hires, growth, model, note }[]` |  | Presets; the first is the BASE plan drawn dashed for comparison. |
| `models` | `{ id, label, share, note, warn? }[]` |  | Inference models, each costing a share of revenue. |
| `start / months` | `string (YYYY-MM) / number` |  | The first projected month and how many (36). |
| `defaultEvents / onEventsChange` | `RunwayEvent[] / (events) => void` |  | Key events: raise and one-off in dollars, contract and recurring in dollars a month. |

## Customising
- Colours: the component reads your shadcn tokens (`--background`, `--foreground`, `--border` …), refined by the `--notchset-*` tokens. The signal colour is `--notchset-signal` (it falls back to `--destructive`). Set tokens on `:root`, or on any container to retheme one area.
- Dark mode follows the `.dark` class on an ancestor (the shadcn and next-themes convention).
- Update later by re-running the install with `--overwrite` (review the diff if you edited it). Changelog: https://beautiful-ui.dev/r/changelog.json

## Keyboard

| Keys | Action |
|---|---|
| ← → / Home / End | Move a lever |
| Enter / Esc | Add the event / close the form |

## Performance

- The projection is a 36-step loop per render; nothing runs while idle.

## Responsive

- Under 860px (container width) the levers move under the chart; the KPIs go two by two under 640px.

## Motion inventory

| Interaction | What moves |
|---|---|
| Any change | The cash line and its dots glide to the new projection (620ms, dots 8ms apart) |
| Lever drag | The thumb squashes while held and settles on release |
| Numbers | Runway and burn roll |

## Accessibility contract (preserve when editing)
- Levers are sliders with value text; arrows, Home and End move them
- The chart is an image labelled with the cash-out month; every number is also in the KPI row
- Plan, model and event type are radio groups; each event's remove button names it

## Install

```bash
npx shadcn@latest add @beautiful-ui-pro/cash-runway
```

Pro item: needs the `@beautiful-ui-pro` registry in `components.json` and `BEAUTIFUL_UI_TOKEN` in `.env.local` (https://beautiful-ui.dev/account). Setup: https://beautiful-ui.dev/docs/pro. Your components.json `style` picks the build: radix-*, new-york and default get Radix, base-* gets Base UI.

## Credits
- Built on shadcn/ui (https://ui.shadcn.com)

The notchset foundation (the tokens listed above, keyframes and motion levels) installs once with the first component; its CSS is public at https://beautiful-ui.dev/r/notchset-foundation.json.
