 * on the track is the default, and a double click puts the value back on it.
 *
 * And it printed the value in the label row, a fixed distance from a thumb that
 * moves, so reading a drag meant looking in two places at once. The value rides
 * the thumb instead.
 *
 * Still a real <input type="range">. Every custom slider on the web reimplements
 * keyboard stepping, touch, and the screen-reader contract, and most of them do
 * one of the three badly; none of what is added here needed the element
 * replaced. Nothing moves that a finger is not moving: the value tracks the

 * one colour transition, short enough to read as immediate and long enough not

    <!--
      vector-editor-rig -- HyperFrames video primitive (ui-props / holdable / demonstrate)

      Concept: a compact vector editor app chrome frames the demonstration. A
      left tool rail, central canvas, and right layers and properties inspector
      stay readable while a blue bezier path draws on live. Anchor dots, diamond
      control handles, connector arms, and a selection frame arrive in sequence
      so the scene reads as active vector design rather than a static diagram.

      Compiled-from evidence: power-reel source 11-vector-editor (design-tool
      twin of terminal-run). The source contributes its blue-on-dark selection
      rig vocabulary, while this primitive adds the required application chrome
      and live pen drawing mechanic.

      Use when: demonstrating vector creation, brand design, drawing tools, or a
      design workflow inside a larger product scene. The primitive is holdable,
      so the completed editor state remains legible for variable scene lengths.

      Variables (declared in data-composition-variables below):
        - tool ("pen" | "shape" | "type", default "pen"): selects the visibly
          active swatch in the left toolbar.
        - pathLabel (string, default "Logo"): names the document chip and the
          selected layer. Blank or whitespace-only values normalize to "Logo".
        - accent is theme-owned, not a getVariables() knob. The path, active tool,
          handles, and selection frame all paint through var(--brand, #0d99ff).

      Envelope (fixed IN/OUT, elastic HOLD only, never gsap.timeScale()):
        IN_BASE  = 1.20s  chrome settles, path draws, rig nodes pop, frame lands
        HOLD     = elastic = max(0, D - (IN_BASE + OUT_BASE)); selected-state dot
                   breathes gently with a finite sine cycle
        OUT_BASE = 0.50s  editor releases upward and fades
        If D < IN_BASE + OUT_BASE, IN and OUT scale down together so IN + OUT == D
        and HOLD == 0.

      Sync point (fixed offset into IN, never inside elastic HOLD): the stroke
      finishes and the final anchor lands at PATH_FINISH_AT = 1.05s into an
      unscaled IN. It scales proportionally when the envelope is compressed.

      Sound cue: a subtle vector-close cue fires at PATH_FINISH_AT. This primitive
      never plays audio. It dispatches an `hf:sfx` CustomEvent
      ({ id: "vector-close", t: PATH_FINISH_AT }) for a scene mix stage to route.

      Mount contract: this file is a MOUNTABLE SUB-COMPOSITION, not a standalone
      composition. A host loads it via data-composition-src; the runtime only
      clones <template> contents, so all live CSS, markup, and scripts sit inside
      <template>. The root has no data-width/data-height. It fills the host slot
      with position:absolute; inset:0; container-type:size and sizes every visual
      from cqw/cqh or SVG viewBox proportions. The root is styled by #root because
      mounted CSS scoping can stop a class selector from matching the flattened
      root. Variables come from window.__hyperframes.getVariables(), which merges
      declared defaults with per-instance host overrides before mount.

    ## Paste it into your composition

    Open `compositions/components/vector-editor-rig.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                            |
    | ----------- | ------- | ---------------------- | --------------------------------------- |
    | `tool`      | `pen`   | `pen`, `shape`, `type` | Tool highlighted in the editor toolbar. |
    | `pathLabel` | `Logo`  | string                 | Name shown for the active vector path.  |

    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="vector-editor-rig"
      data-composition-src="compositions/components/vector-editor-rig.html"
      data-variable-values='{"tool":"pen","pathLabel":"Logo"}'
    ></div>
    ```

    Tagged `prop` `ui-props` `demonstrate` `vector` `design-tool` `pen-tool` `bezier` `app-chrome`.
