# Panel line (Notchset): prompt.md (v2.0.0)

- id: `panel-line` · version 2.0.0 · block · pro (Pro)
- category: Application UI
- build: one set of files for every shadcn style
- install: `npx shadcn@latest add @notchset-pro/panel-line`
- npm dependencies: lucide-react@^1

- The install command carries everything this item needs (files, CSS, tokens, npm and registry dependencies). Prefer it to copying source by hand.

The counts in three standings over a segmented bar, then every marker as an ink tick standing as tall as its value sits from the middle of its own range; out of range rise with a warn dot. Point to read one; the clinician's picks above. Plays a new panel's arrival..

## Build it
- Stack: React 18.3 or 19, TypeScript, Tailwind CSS v4 utility classes on the foundation's roles, a components.json (imports use its aliases).
- Packages: `lucide-react@^1`.
- Files: `components/ui/notchset/blocks/panel-line.tsx`; shared code: `lib/notchset/physics.ts`, `lib/notchset/standing.ts`.
- Registry dependencies, installed with it automatically: shadcn `utils` (cn), `notchset-foundation`, `button`, `rolling-number`.
- Builds: one set of files, the same for every shadcn style.
- Exports to keep: `PanelLine`, `fromMiddle`, and every exported type.
- CSS: the install adds the notchset foundation (its roles, keyframes and motion switch, reading your shadcn tokens for colour) 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.
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- This item reads `--ns-canvas`, `--ns-deep`, `--ns-deep-ink`, `--ns-deep-ink-2`, `--ns-deep-line`, `--ns-font-display`, `--ns-font-mono`, `--ns-ink`, `--ns-ink-3`, `--ns-line`, `--ns-ok`, `--ns-radius-card`, `--ns-series`, `--ns-signal`, `--ns-standing-critical`, `--ns-standing-in`, `--ns-standing-out`, `--ns-text-figure`, `--ns-text-meta`, `--ns-text-small`, `--ns-text-title`, `--ns-tracking-display`, `--ns-weight-medium`.
- Retune it (on any ancestor) with the foundation's roles and hooks: `--ns-bad`, `--ns-bad-ink`, `--ns-band`, `--ns-band-edge`, `--ns-band-grade`, `--ns-band-optimal`, `--ns-beat`, `--ns-bezel`, `--ns-canvas`, `--ns-cat-1`, `--ns-cat-2`, `--ns-cat-3`, `--ns-cat-4`, `--ns-cat-5`, `--ns-cat-6`, `--ns-check`, `--ns-chip`, `--ns-control`, `--ns-control-pad`, `--ns-control-sm`, `--ns-deep`, `--ns-deep-ink`, `--ns-deep-ink-2`, `--ns-deep-line`, `--ns-dialog`, `--ns-dialog-lg`, `--ns-dialog-sm`, `--ns-ease`, `--ns-ease-in`, `--ns-ease-panel`, `--ns-ease-pop`, `--ns-field`, `--ns-flood-arc`, `--ns-flood-aurora`, `--ns-flood-behind-1`, `--ns-flood-behind-2`, `--ns-flood-bloom`, `--ns-flood-deep`, `--ns-flood-dial-bloom`, `--ns-flood-glass`, `--ns-flood-grain`, `--ns-flood-image`, `--ns-flood-ink`, `--ns-flood-ink-low`, `--ns-flood-light`, `--ns-flood-mid`, `--ns-flood-pale`, `--ns-flood-pane`, `--ns-flood-pane-edge`, `--ns-flood-pill-ink`, `--ns-flood-ribbon`, `--ns-flood-ribbon-core`, `--ns-flood-shadow`, `--ns-flood-sheen`, `--ns-flood-wash`, `--ns-font-body`, `--ns-font-display`, `--ns-font-mono`, `--ns-font-script`, `--ns-glass`, `--ns-glass-blur`, `--ns-glass-shadow`, `--ns-glow`, `--ns-grain`, `--ns-gutter`, `--ns-header`, `--ns-heat`, `--ns-hover`, `--ns-ink`, `--ns-ink-2`, `--ns-ink-3`, `--ns-ink-4`, `--ns-leading`, `--ns-lift`, `--ns-light-1`, `--ns-light-2`, `--ns-light-3`, `--ns-light-spread`, `--ns-light-strength`, `--ns-line`, `--ns-line-soft`, `--ns-lit-edge`, `--ns-menu-dy`, `--ns-menu-row`, `--ns-mesh`, `--ns-mesh-frost`, `--ns-ok`, `--ns-ok-ink`, `--ns-orb-body`, `--ns-orb-cool`, `--ns-orb-core`, `--ns-orb-dawn`, `--ns-orb-deep`, `--ns-orb-edge`, `--ns-orb-grain`, `--ns-orb-ground`, `--ns-orb-halo`, `--ns-orb-inner`, `--ns-orb-key`, `--ns-orb-lift`, `--ns-orb-limb`, `--ns-orb-limb-from`, `--ns-orb-rim`, `--ns-orb-skin-hi`, `--ns-orb-skin-lo`, `--ns-orb-skin-mid`, `--ns-orb-warm`, `--ns-panel`, `--ns-panel-w`, `--ns-prism-edge`, `--ns-prism-glint`, `--ns-prism-sheen`, `--ns-prism-tint`, `--ns-pulse`, `--ns-radius`, `--ns-radius-card`, `--ns-radius-full`, `--ns-radius-lg`, `--ns-radius-sm`, `--ns-radius-xl`, `--ns-raised`, `--ns-range`, `--ns-row`, `--ns-row-compact`, `--ns-segment`, `--ns-selected`, `--ns-series`, `--ns-series-core`, `--ns-series-lilac`, `--ns-series-tint`, `--ns-shadow-dialog`, `--ns-shadow-float`, `--ns-shadow-panel`, `--ns-sheet`, `--ns-sheet-bottom`, `--ns-side`, `--ns-signal`, `--ns-sleep-awake`, `--ns-sleep-deep`, `--ns-sleep-light`, `--ns-sleep-rem`, `--ns-space-1`, `--ns-space-2`, `--ns-space-3`, `--ns-space-4`, `--ns-space-5`, `--ns-space-6`, `--ns-space-8`, `--ns-space-section`, `--ns-stack-on`, `--ns-standing-critical`, `--ns-standing-in`, `--ns-standing-out`, `--ns-state-doing`, `--ns-state-done`, `--ns-state-review`, `--ns-state-todo`, `--ns-switch-h`, `--ns-switch-w`, `--ns-text-body`, `--ns-text-control`, `--ns-text-display`, `--ns-text-figure`, `--ns-text-headline`, `--ns-text-hero`, `--ns-text-lede`, `--ns-text-meta`, `--ns-text-page`, `--ns-text-record`, `--ns-text-small`, `--ns-text-strong`, `--ns-text-sub`, `--ns-text-title`, `--ns-tile-shadow`, `--ns-time-born`, `--ns-time-color`, `--ns-time-dialog`, `--ns-time-menu`, `--ns-time-page`, `--ns-time-panel`, `--ns-time-toast`, `--ns-tint`, `--ns-tint-ink`, `--ns-toast-bottom`, `--ns-toast-left`, `--ns-touch`, `--ns-tracking-display`, `--ns-tracking-headline`, `--ns-warn`, `--ns-warn-ink`, `--ns-wash-clay`, `--ns-wash-dusk`, `--ns-wash-graphite`, `--ns-wash-ink`, `--ns-wash-sage`, `--ns-wash-sand`, `--ns-weight-light`, `--ns-weight-medium`, `--ns-weight-regular`, `--ns-weight-strong`, `--ns-well`.
- Never add Tailwind colour classes inside the component.

```tsx
import { PanelLine } from "@/components/ui/notchset/blocks/panel-line";
```

## Parts
- A single export that takes props.

## Match the original
- Read `components/ui/notchset/blocks/panel-line.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

### Not when

## Built from
- button (`button`), installed with it: reuse it, don't rebuild it
- rolling-number (`rolling-number`), installed with it: reuse it, don't rebuild it
- Physics (shared helper, ships with it)
- Standing (shared helper, ships with it)

## Mistakes
- Recreating the component instead of installing it

## Usage

```tsx
"use client";
import { PanelLine } from "@/components/ui/notchset/blocks/panel-line";

const SYS = ["Heart", "Heart", "Heart", "Metabolic", "Metabolic", "Nutrients", "Nutrients", "Nutrients", "Thyroid", "Thyroid", "Blood", "Blood"];
const ITEMS = [
  ["LDL cholesterol", 128, "mg/dL", undefined, 99],
  ["ApoB", 98, "mg/dL", undefined, 99],
  ["HDL cholesterol", 61, "mg/dL", 50, undefined],
  ["Fasting glucose", 86, "mg/dL", 65, 99],
  ["Uric acid", 6.3, "mg/dL", 2.4, 6.0],
  ["Vitamin D", 41, "ng/mL", 30, 100],
  ["Ferritin", 48, "ng/mL", 30, 150],
  ["Vitamin B12", 540, "pg/mL", 232, 1245],
  ["TSH", 2.3, "mIU/L", 0.45, 4.5],
  ["Free T4", 1.18, "ng/dL", 0.82, 1.77],
  ["Haemoglobin", 13.2, "g/dL", 11.1, 15.9],
  ["Platelets", 255, "×10³/µL", 150, 450],
] as const;

export default function PanelLineDemo() {
  return (
    <PanelLine
      title="Your biomarkers"
      label="Follow-up panel · drawn 16 Oct · Northside Lab"
      items={ITEMS.map(([name, value, unit, low, high], i) => ({ id: String(i), name, system: SYS[i]!, value, unit, low, high }))}
      picks={{ by: "Dr. Priya Rao", initials: "PR", ids: ["0", "1", "5"] }}
    />
  );
}
```

## Props

| Prop | Type | Default | What it does |
|---|---|---|---|
| `title` | `string` |  | Required. |
| `label` | `string` |  | which panel: "Follow-up panel · 16 Oct · Northside Lab" |
| `items` | `PanelLineItem[]` |  | Required. |
| `onOpen` | `(id: string) => void` |  |  |
| `action` | `{ label: string; onClick: () => void }` |  |  |
| `picks` | `{ by: string; initials: string; ids: string[] }` |  | the markers a clinician picked to watch, with who picked them (their initials stand for them) |
| `tone` | `"deep" \| "ground"` | `"deep"` | on its own dark band (deep), or drawn in fine ink straight on the page's ground |
| `reading` | `string` |  | a marker read at rest (a still for a review or the first visit): its id |
| `arrive` | `number \| null` |  | A new panel arriving, 0 to 1 (the host's clock): the ticks rise into place one system at a time and those out of range last, each landing with its warn dot; the counts roll as they land. Left out, the panel is simply there. |
| `backInRange` | `string` |  | a marker that came back into range on this panel: it gets the one ok glow pulse as it lands |
| `scale` | `number` | `1` | how tall the line stands (2 when it's the page's signature object) |

## Customising
- Colours: every part reads the foundation's roles (`--ns-canvas`, `--ns-ink`, `--ns-line`, `--ns-signal` …), which read your shadcn tokens (`--background`, `--foreground`, `--border`, `--destructive` …), plus the optional `--success` and `--warning`. Retheme on `:root` or any container; never add Tailwind colour classes inside the component.
- Dark mode follows the `.dark` class or `data-theme="dark"` on an ancestor (the shadcn and next-themes conventions).
- Update later: Commit or stash local changes first (or copy the files), so the update can be undone. Read https://notchset.dev/r/changelog.json for the new versions: a major version, an entry marked breaking or a merge says what to change. Then re-run the install with `--overwrite`, on a branch. It replaces the component's files, the shared helper files they import, and the item's CSS rules in the global stylesheet, so review the whole diff (components, shared files, CSS), re-apply your own edits, and run the app's typecheck, tests and build.

## Accessibility contract (preserve when editing)

## Install

```bash
npx shadcn@latest add @notchset-pro/panel-line
```

Pro item: needs the `@notchset-pro` registry in `components.json` and `NOTCHSET_TOKEN` in `.env.local` (https://notchset.dev/account). Setup: https://notchset.dev/docs/pro. Every components.json `style` gets the same files.

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