## Summary
- **API**: POST (create), DELETE (delete), PATCH (rename/move), POST duplicate endpoints with null-byte sanitization
- **FileTree**: right-click context menu with New File, New Folder, Rename, Duplicate, Delete
- **Drag-and-drop**: move files between folders with visual feedback and subtree guard
- **Inline editing**: rename/create inputs with filename validation
- **Header actions**: quick New File / New Folder buttons in the FILES header
Stacks on top of `feat/studio-code-quality`.
## Test plan
- [x] Right-click file → Rename, Delete, Duplicate all work
- [x] Right-click folder → New File, New Folder, Delete work
- [x] Drag file from one folder to another
- [x] Create file with invalid name (`../foo`, `a/b`) → rejected client-side
- [x] Delete currently-edited file → editor clears
- [x] Studio build succeeds
## Summary
The timeline is now hidden by default. A toggle button appears in both the header (alongside panel toggles) and the player controls bar. Both sync the same state and turn teal when the timeline is visible.
## Changes
- **`timelineVisible` state** in `App.tsx`, defaults to `false`
- **Header toggle**: icon button between sidebar toggle and Renders button
- **Player controls toggle**: icon button at the right end of the controls bar
- **NLELayout**: `timelineVisible` and `onToggleTimeline` props gate the timeline + resize divider
- **Player controls stay visible**: moved from inside the timeline section to inside the preview area, so hiding the timeline doesn't hide play/seek/timecode
## Behavior
| State | Preview | Player controls | Timeline |
|---|---|---|---|
| Timeline hidden (default) | Full height | ✅ Visible | Hidden |
| Timeline visible | Shorter | ✅ Visible | Shown with resize handle |
Both toggle buttons show identical teal active state (`#3CE6AC/10` bg + `#3CE6AC/30` border).

## Summary
Removes the `ProjectPicker` home screen entirely. The studio now boots directly into the editor by auto-selecting the first available project from `/api/projects`.
## Changes
- **Auto-select on load**: When no `#project/` hash is present, fetches the project list and navigates to the first one
- **Type narrowing**: Added `if (resolving || !projectId)` early return so TypeScript narrows `projectId` to `string` for all downstream props
- **Removed**: `ProjectPicker`, `ProjectCard`, `ExpandedPreviewIframe` components (~280 lines), `handleSelectProject` callback, `ProjectEntry` interface
## Why
The CLI studio always has exactly one project. The home page was an extra click with no value.

## Summary
- Surfaces error message when render fails due to producer server not running
- Two cases covered: initial POST failure and SSE connection drop
- Failed jobs now show the error reason in red text in the Renders panel
## Test plan
- [x] Start studio without producer server
- [x] Click render → should show "Could not reach render server" in red
- [x] Start render then kill producer → should show "Connection lost"

## Summary
- CLI render: use timestamped filenames (`project_date_time.ext`) matching the studio's naming convention, preventing overwrites of previous renders
- studioServer: read `fps`/`quality`/`format` from POST body instead of hardcoding `fps:30`/`quality:standard`/`mp4`
- studioServer: use timestamped job IDs matching the studio pattern
- studioServer: fix download endpoint to serve correct content-type for WebM
## Test plan
- [x] `hyperframes render --format webm` outputs timestamped WebM file
- [x] `hyperframes render` outputs timestamped MP4 (no overwrite)
- [x] Studio embedded server (`hyperframes dev`) renders with correct format when selected in UI
- [x] Download endpoint serves correct MIME type for WebM renders
## Summary
- Add render queue panel with progress tracking, download, and delete actions
- Restructure App layout: home page with project picker, session-based routing
- Add ExpandOnHover component for preview-on-hover interactions (uses motion/react)
- CompositionsTab now supports hover preview with expanded iframe view
- Vite config: guard setInterval cleanup to dev-only (fixes CI build timeout)
- Add favicon and update studio package deps
## Test plan
- [x] Render queue shows progress, completes, and allows download
- [x] Home page lists projects and navigates to session view
- [x] ExpandOnHover shows expanded preview on mouse hover with spring animation
- [x] `vite build` exits cleanly (no hanging process from setInterval)

## Summary
- Add collapsible left sidebar with Compositions and Assets tabs
- Compositions tab lists all sub-compositions with thumbnail previews and navigation
- Clicking a composition opens it in the code editor AND navigates the preview to show that composition
- Assets tab categorizes project files by type (images, fonts, media)
- Race condition guard on composition fetch with functional state update
- Thumbnail error fallback shows name initial instead of empty box
## Test plan
- [x] Sidebar opens/closes with smooth transition
- [x] Compositions tab lists files from project API
- [x] Clicking a composition changes the preview iframe to that composition
- [x] Assets tab categorizes files by type

## Summary
- Replace Split/Delete buttons with Edit Range toolbar
- Edit button opens a time-range selection on the timeline
- "Copy to Agent" exports the selected range as a prompt-ready description
- Range selection shows start/end times with drag handles

## Summary
- **NLELayout**: Add toolbar slot, composition breadcrumb navigation, improved responsive layout
- **Vite config**: Add full project API (preview, thumbnail, render, file CRUD) for standalone dev mode
- Remove AgentActivityTrack component (replaced by timeline clips)
- Add HTML editor utilities for composition source editing
- Guard setInterval cleanup to dev-only to prevent `vite build` from hanging in CI

## Summary
- Add zoom state (zoomMode, pixelsPerSecond) to player store
- Add timeline element updates (setElements, clearElements)
- Remove unused/duplicate exports from player barrel file

The blank template was a bare `<div>` fragment without `<!DOCTYPE>`,
`<head>`, or `<body>`. This caused:
- Blank preview (bundler/runtime can't initialize from a fragment)
- "Failed to run lint" (parsing errors on the malformed document)
All other templates (swiss-grid, vignelli, warm-grain, play-mode) are
proper HTML documents — blank was the only outlier.
Also improves lint error reporting to show the actual error message
instead of the generic "Failed to run lint."

When installed via npx, `hyperframes dev` now starts a standalone
Hono HTTP server that serves the pre-built studio SPA and implements
the project API (file listing, read/write, preview bundling,
sub-composition rendering, runtime serving, SSE file watching).
Three modes are auto-detected:
1. Monorepo dev (running from .ts source) → spawn Vite (existing)
2. Local @hyperframes/studio installed → spawn Vite via package (new)
3. Default → embedded Hono server (new, zero extra deps needed)
Also patches the studio SPA to use EventSource SSE fallback when
Vite HMR is unavailable (production/embedded builds).

* feat: initial code port from hyperframes-internal
Port all OSS-ready packages from the internal monorepo:
- @hyperframes/core — shared types, HTML generation, GSAP utilities, runtime
- @hyperframes/cli — CLI for creating, previewing, and rendering compositions
- @hyperframes/engine — framework-agnostic rendering engine (BeginFrame + FFmpeg)
- @hyperframes/producer — video rendering pipeline (Puppeteer + FFmpeg)
- @hyperframes/ui-player — browser-based video player component
- @hyperframes/studio — composition editor (React frontend + Hono backend)
Includes regression test suite with Docker-based test harness.
All HeyGen-internal references, deployment infrastructure, and
proprietary assets have been removed. Package names migrated
from @app/* to @hyperframes/*.
