Add Zelda BOTW (Sheikah Slate) UI style rule

[chaos-xxl]

Adds a Cursor rule for building UIs in the Zelda: Breath of the Wild (Sheikah Slate) visual style.

Contribution Type

• New rule (.mdc) + README registration
• Fix / improvement to an existing rule
• Docs / other

Value To Cursor Users

Gives Cursor a reusable, self-contained visual-style rule so it can generate UIs in the distinctive BOTW "Sheikah Slate" look consistently — dark theme, the signature double-border pattern, Sheikah-blue glow, italic body / Hylia Serif titles — without the user re-specifying it each time. Backed by the open-source zelda-hyrule-ui React library (83 components, MIT), so generated markup maps to a real component set if desired.

Added Or Changed Files

• Added rules/zelda-botw-sheikah-slate-cursorrules-prompt-file.mdc — the rule, with required description / globs / alwaysApply frontmatter, design hard-rules, color tokens, a copy-paste double-border snippet, and a "never approximate the signature assets/font" guardrail.
• Changed README.md — one linked bullet under Frontend Frameworks and Libraries (alphabetical, end of section).

Quality Checklist

• .mdc starts with valid frontmatter (description, globs, alwaysApply: false)
• README entry is a single line, links to the rule file, follows existing format
• Placed in the appropriate category, alphabetical order preserved
• Content is original (authored by me), neutral, and practical
• No promotional / SaaS funnel; no paid dependency

Notes For Maintainers

zelda-hyrule-ui is an unofficial, non-commercial fan project, not affiliated with Nintendo. The rule describes an original visual-style spec (colors, borders, tokens) and does not redistribute any Nintendo assets. Happy to adjust the category (Frontend Frameworks vs CSS and Styling) or wording if you prefer.
