/*
* ExHentai Download Button with Batch Support
*
* This userscript enhances ExHentai/E-Hentai gallery pages by adding:
* - Individual download buttons for each gallery (Original, Resample, H@H)
* - Batch download functionality with progress tracking
* - Error logging and retry capabilities
* - Toast notifications for H@H operations
*
* Part of the ExHentai Utilities toolkit:
* https://github.com/troyt-666/exhentai-utilities
*
* Installation:
* 1. Install Tampermonkey or compatible userscript manager
* 2. Click on this script's raw URL
* 3. Tampermonkey will prompt to install
*
* Usage:
* - Individual downloads: Click buttons on each gallery
* - Batch downloads: Use checkboxes and batch panel (top-right)
* - H@H downloads are queued to your Hentai@Home client
*
* Note: All downloads follow standard ExHentai rules and consume GP
