dsh-fgo-chaldea

The stock DeepSeek Harness Web UI is functional yet visually neutral. dsh-fgo-chaldea wraps the entire interface in a Chaldea-inspired atmosphere: a deep starry-navy backdrop, blue-and-gold palettes, and gold-etched border accents that lend your daily model conversations a quiet sense of ritual.

Five themes are bundled—Chaldea Night, Chaldea Dawn, Artoria Blue-Gold, Morgan Black-Purple, and Mash White-Purple—spanning both dark and light color schemes. The backdrop layer is not a pasted static image; it is generated deterministically in the browser as original star charts, magic circles, celestial rings, and a golden horizon line, each theme carrying its own palette. No image files are shipped, and no official FGO artwork is included. Gold hairline rules and four-corner engravings live on independent pointer-events:none decoration layers that recolor with the active skin. All colors are registered through the official ctx.theme token API; a subtle fade-and-breathe animation honors the system prefers-reduced-motion preference. Uninstalling restores the theme, backdrop, and token overrides completely, returning the UI to its native DSH look.

The plugin touches only the display layer—it never reads or mutates session data, model requests, or workspace content. Theme choice persists in localStorage and survives page refreshes. It is built for FGO players, developers who want their daily tools to match their aesthetic, or anyone who simply enjoys customizing the screen they stare at all day. A fan-made project released under the MIT license, with no affiliation to TYPE-MOON, Aniplex, Lasengle, or the FGO team.
