v0.3.0

### Fixed

• Color emoji rendering now works properly with LuaLaTeX using the HarfBuzz renderer for Noto Color Emoji.
• Fixed option comparison logic in superemoji.sty using \ifdefstring instead of \ifx.

### Changed

• LuaLaTeX is now the recommended engine for color emoji support (style=color).
• XeLaTeX still works for B&W emoji via Segoe UI Emoji.
• Updated documentation PDF compiled with LuaLaTeX showing working color emoji examples.

### Usage

For color emoji:
\documentclass{article}
\usepackage[style=color]{superemoji}
\begin{document}
Status: \emoji{status-ok1}
\end{document}

Compile with lualatex and ensure Noto Color Emoji is installed on your system.
