csstyle 2026.7.1

save_a4() now renders PNGs with the ragg AGG device (ragg::agg_png) instead of the default grDevices PNG device. This is markedly faster for busy, many-geom ggplots (and patchwork composites) at full A4 / 300 dpi, and produces cleaner text. Non-PNG filenames fall back to ggsave's extension-based device selection, so behaviour is unchanged for them. ragg added to Imports.
