Reorganize repository images for clearer structure: moved several GIFs (blockquotes, custom-callouts, hover-effects, hover-effects-2, link-hovers, lists-checkboxes, showcase) into ASSETS/Screenshots; removed ASSETS/Screenshots/electric-current.png; moved neon-acid (1).png from ASSETS/Screenshots to ASSETS; relocated obsidian-theme image into ASSETS.
Add animated GIF assets demonstrating key features: blockquotes, custom callouts, link hovers, lists with checkboxes, and a general showcase. These assets are intended for use in documentation or README to visually showcase theme capabilities.
Add comprehensive demo file showcasing all Neon Acid theme features, including typography, callouts, code blocks, tables, images, and UI elements. Serves as a visual stress test and reference for theme implementation and customization.
Rename Screenshots/* → ASSETS/Screenshots/* and update README image URLs. Major cleanup and rewrite of theme.css: add :root tokens, consolidate neon color variables, restructure image, code-block, table and callout styles, improve syntax token colors, hover effects, and reduced-motion support. Also remove duplicated README header and tweak content organization. Primarily a styling/documentation refactor to centralize assets and modernize the theme.
Add manifest.json with package metadata; add new assets (logo, callouts gif, screenshots) and remove icon.gif. Update README header to use the beakers asset and rename a screenshot. Expand theme.css with multiple neon-themed UI tweaks: header icon, folder icon, animations, keyframes, and a set of illustrated callout styles and variants referencing the new assets.
