dsh-pixel-crt: Dark CRT Pixel Skin for DSH Chat Area

dsh-pixel-crt is a DSH plugin maintained by kingdawangXTA (fun dress-up category) that transforms the Web GUI's chat area and input area into a dark CRT pixel style, featuring hard 2px borders, blocky shadows (3px 3px 0), bitmap font titles, and scanlines. It includes a post-render debounce contrast cleanup to prevent light text on dark backgrounds within cards. The plugin only affects the "chat" and "composer" regions without modifying layout, font sizes, or message spacing, nor does it write to disk. Installation is done via `dsh plugin add <repo address>` or `dsh plugin install ./pixel-crt`, requiring a Web GUI reload after completion. Known limitations include slightly thick icon buttons, fixed 16px titles, and scanlines that can be disabled using a single CSS rule. Licensed under MIT; it is recommended to inspect the source code before installation.
