TriFrost 0.23.0

This release further sharpens TriFrost’s internals, making the createCss system more flexible for external libraries by respecting --prefixed variables and tuning the JSX engine for even faster prop rendering.

Improved

• feat: createCss will no longer prefix a variable with --v- if the variable's name starts with --.
• feat: createCss will no longer prefix a theme variable with --t- if the variable's name starts with --.

createCss({
    var: {
        font_header: '...',
        font_body: '...',
        '--something': '...'
    },
    theme: {
        body_bg: {...},
        body_fg: {...},
        '--someborder': {...},
    },
});
/* Will now result in: --v-font_header, --v-font_header, --something, --t-body_bg, --t-body_fg, --someborder */

• perf: The JSX runtime will now fallback to null for props instead of an empty object, allowing for a micro optimization in the render engine to short-circuit prop rendering.

The performance change in the JSX prop short-circuiting leads to an estimated 5-10% render performance boost 🚀 (based on vitest bench snapshots of common JSX trees), without sacrificing determinism or memory safety.
