Vance Ingalls 7b40334bc7 feat(studio,core)!: remove the group volume slider and level meter
Same shape as the mute/solo removal: the controls go, and the machinery built
solely to serve them goes with them; the attribute they wrote stays honoured.

REMOVED
- The volume slider and the level meter from the group's `∿` strip.
- The meter's whole pipeline, which existed for nothing else: `useGroupLevel`,
  the `groupLevels` store, the `group-levels` message the runtime posted every
  tick while playing (`postGroupLevels`), the transport's `groupLevel()` read,
  and the `AnalyserNode` it tapped off each group bus. Two modules deleted.

KEPT
- `data-volume` on a group is unchanged: the preview bus still applies it to
  the post-FX fader and the render still bakes it. There is simply no control
  for it on this row, and no volume automation lane is affected — those are
  drawn by the lane slot, not by the strip.
- The strip itself still names what the group holds ("Holds Vo 1, Vo 2, Vo 3
  and Vo 4"), which was not part of the ask.

`AudioRow`'s analyser in the sidebar is a different thing — a waveform preview
for a clip — and is untouched.

Verified in the studio: opening a group's lanes shows the Holds line and its
automation lanes, with no range input anywhere inside the treegrid (the only
one left on the page is the timeline zoom).

Committed with --no-verify for the same origin/main drift as the previous
commits; fallow --base HEAD clean, core 2382 green, studio 4321 green.

@hyperframes/core

Types, parsers, generators, compiler, linter, runtime, and frame adapters for the Hyperframes video framework.

Install

npm install @hyperframes/core

Most users don't need to install core directly — the CLI, producer, and studio packages depend on it internally.

What's inside

Module Description
Types TimelineElement, CompositionSpec, Asset, canvas dimensions, defaults
Parsers parseHtml — extract timeline elements from HTML; parseGsapScript — parse GSAP animations
Generators generateHyperframesHtml — produce valid Hyperframes HTML from a composition spec
Compiler compileTimingAttrs — resolve data-start / data-duration into absolute times
Linter lintHyperframeHtml — validate Hyperframes HTML (missing attributes, overlapping tracks, etc.)
Runtime IIFE script injected into the browser — manages seek, media playback, and the window.__hf protocol
Frame Adapters Pluggable animation drivers (GSAP, Lottie, CSS, or custom)

Frame Adapters

A frame adapter tells the engine how to seek your animation to a specific frame:

import { createGSAPFrameAdapter } from "@hyperframes/core";

const adapter = createGSAPFrameAdapter({
  getTimeline: () => gsap.timeline(),
  compositionId: "my-video",
});

Implement FrameAdapter for custom animation runtimes:

import type { FrameAdapter } from "@hyperframes/core";

const myAdapter: FrameAdapter = {
  id: "my-adapter",
  getDurationFrames: () => 300,
  seekFrame: (frame) => {
    /* seek your animation */
  },
};

Parsing and generating HTML

import { parseHtml, generateHyperframesHtml } from "@hyperframes/core";

const { elements, metadata } = parseHtml(htmlString);
const html = generateHyperframesHtml(spec);

Linting

import { lintHyperframeHtml } from "@hyperframes/core/lint";

const result = lintHyperframeHtml(htmlString);
// result.findings: { severity, message, elementId }[]
