/**
 * Button Component Styles
 *
 * Three appearance variants × six semantic flavors × three tones (+/base/-).
 * Each variant uses ONE token system:
 *   - solid    → --ty-solid-{flavor}-{strong|base|soft}  (bg) + --ty-solid-{flavor}-fg (text)
 *   - outlined → --ty-color-{flavor}-{strong|base|soft}  (text === border)
 *   - ghost    → --ty-color-{flavor}-{strong|base|soft}  (text), --ty-bg-{flavor}-soft (hover)
 *
 * Per-instance overrides via host CSS variables:
 *   --ty-button-bg, --ty-button-bg-hover, --ty-button-color, --ty-button-border
