Animated GIF image fills keep their frames (first frame on the canvas and in exports; the presenter and preview play them, capped frames and memory, idle when not playing). TIFF images open, import, place and drop (pure-Rust decoder already in the tree); SVG exports embed TIFF and BMP as PNG. HEIC and video stay out (non-Rust decoders).
