gsp-style

This is a standalone composable skill. It works two ways:

1. Standalone — user runs /gsp-style cyberpunk directly, gets visual preview + tokens
2. As a building block — agents invoke this skill during workflows, getting tokens only

Input: Style name(s), optional flags (--list, --preview) Output: {preset-name}.yml + STYLE.md + INDEX.md in the target system directory Agent: None — token expansion from YAML presets is handled inline
