Build this tool: YouTube Video URL Extractor
Product folder name: YouTube Video URL Extractor

PRODUCT BRIEF
Paste any YouTube channel (@handle, channel URL, or UC… id). Pull every public
upload — Shorts and long-form — with title + watch URL + duration + published
date. Filter All / Shorts only / Long only. Export CSV (Excel-friendly UTF-8 BOM)
or copy URLs / report text.

CONTEXT
Difficulty: Easy
Category: People & Blogs / Creator business
No Gemini — YouTube Data API key only (shared CaseyBuilds youtube_settings.json).

WHY THIS TOOL
Creators need a full channel URL dump for audits, affiliate scans, description
cleanup, and cross-post planning — without scraping Studio by hand.

STACK (standalone desktop app)
- Python 3 + tkinter GUI — standalone desktop tool (not a website).
- Include: main .py, requirements.txt, run_*.bat, build_exe.bat (PyInstaller),
  casey_youtube_setup.py, YOUTUBE_SETUP.txt, exports/, thumbnails/, VIDEO_SCRIPT.txt.
- Smoke-test core logic offline without requiring live API keys when possible.

GUI RULES
- Casey dark theme (navy / amber / teal).
- Brand lockup CASEY BUILDS IT + hero title split (white + amber accent).
- How to use: one muted sentence under the title.
- Left: API key (masked Save + help), channel field, Fetch, filter, Export / Copy.
- Right: Treeview of Type · Length · Title · URL · Published.
- No ttk.Combobox — use DarkSelect / Menubutton for filter.
- WM_DELETE_WINDOW on close.
- Background thread for fetch; status line for progress.

API
- Shared key via casey_youtube_setup (LOCALAPPDATA\CaseyBuilds\youtube_settings.json).
- channels.list → uploads playlist → playlistItems.list (paged) → videos.list
  batches of 50 for duration + privacy.
- Short = duration ≤ 180 seconds (current YouTube Shorts max). Long = everything else.
- Skip private/deleted playlist placeholders.

EXPORT
- CSV columns: title, url, video_id, type, duration, duration_sec, published_at,
  privacy, channel_title, channel_id, channel_url.
- UTF-8 with BOM for Excel. Saved under exports\.
