Move artwork images into dist/images/Artwork and update gallery paths

[ethan-CCY]

Motivation

• Organize uploaded artwork assets into the web-serving dist/images/Artwork directory for correct runtime paths and deployment.
• Ensure filenames are web-safe (no spaces/capitalization) so they reliably load in browsers and static hosts.

Description

• Moved the uploaded Artwork files into dist/images/Artwork and renamed them to kebab-case (for example 01_Quiet Corner.jpeg → 01-quiet-corner.jpeg).
• Updated gallery image sources in index.html to point at the new paths under dist/images/Artwork (updated src attributes for the three featured images).
• Committed the changes with a descriptive message and updated the repository index accordingly.

Testing

• Served the site locally with python -m http.server 8000 and verified the gallery page rendered successfully.
• Ran a Playwright script to capture a screenshot (artifacts/artwork-gallery.png) of http://127.0.0.1:8000/index.html, which completed successfully and confirmed images load.
• Performed a local git commit which succeeded (files renamed and index.html modified).
