# Conic Progress Ring

> A token-driven conic progress ring whose angular fill and center count settle together from one registered percentage.

## Install

<InstallCommand command="npx hyperframes add conic-progress-ring" />

That writes one file: `compositions/components/conic-progress-ring.html`.

## Paste it into your composition

Open `compositions/components/conic-progress-ring.html` and copy what is inside into your own composition.

A component has no size or duration of its own. It takes both from the composition
you paste it into.

## Variables

Every one of these has a default, so the piece works untouched. Set the ones you
want to change on the element:

| Variable    | Default | Accepts             | What it does                                                          |
| ----------- | ------- | ------------------- | --------------------------------------------------------------------- |
| `progress`  | `100`   | 0% to 100%, step 1% | Target angular fill from 0 to 100.                                    |
| `thickness` | `12`    | 4% to 30%, step 1%  | Ring stroke thickness as a percent of the ring radius.                |
| `label`     | `100`   | string              | Numeric target shown in the center and counted in sync with the fill. |

Set them with `data-variable-values` on the element that mounts it. These are the
defaults, so this behaves exactly like the preview above until you change one:

```html wrap theme={null}
<div
  data-composition-id="conic-progress-ring"
  data-composition-src="compositions/components/conic-progress-ring.html"
  data-variable-values='{"progress":100,"thickness":12,"label":"100"}'
></div>
```

    conic-progress-ring: HyperFrames video primitive (data / prove / demonstrate)

    Concept: one registered percentage moves the hard frontier of a conic
    gradient while a radial mask cuts out the center. The center value is
    derived from that same percentage on every GSAP update, so fill and count
    cannot drift apart.

    Compiled-from evidence: hyperframes-research-css-gems.md, section 10,
    "Registered conic progress ring". The finding specifies a typed percentage
    as the seek handle for a conic-gradient frontier and a radial mask for the
    ring cutout.

    Use when: a scene needs to prove completion, attainment, or a measured
    result with one immediately legible data mark.

    Variables:
      progress  number  0 to 100  default 100  target angular fill
      thickness number  4 to 30   default 12   ring stroke as a percent
      label     string            default "100" center count target

    Envelope:
      IN   1.40s fixed fill and synchronized count, power2.out
      HOLD elastic and deliberately still after the result settles
      OUT  0.50s fixed opacity release, power2.in
      For durations shorter than 1.90s, IN and OUT scale together. HOLD is the
      only elastic phase. The timeline is never time-scaled.

    Sync point:
      progress-settled at the end of IN, always outside the elastic HOLD

    Sound cues: none. A data proof should not claim an audio event for its host.

    Mount contract: this file is a template-wrapped sub-composition. The host
    owns dimensions. #root fills that box with inset:0 and has no data-width or
    data-height. The hardcoded composition id matches the root and timeline key.
