Enum Phase 

pub enum Phase {
    Build = 0,
    Clone = 1,
    Interpret = 2,
    Gpu = 3,
    Frame = 4,
    Present = 5,
}

Frame phases attributed to CPU vs GPU so a baseline can split the ~16 ms budget.

Variants

Build = 0

UI thread: tree.commands() flatten + dev.on_frame.

Clone = 1

UI thread: the per-frame Vec<DrawCommand> clone handed to the render thread.

Interpret = 2

Render thread: analyze_frame (dirty/scroll detection) + interpret_commands.

Gpu = 3

Render thread: segment build + pass execution + queue.submit (encompasses present).

Frame = 4

Whole render_frame (render thread) or whole SW render (UI thread).

Present = 5

Render thread: output.present() alone — a subset of gpu that isolates swapchain/vsync block (FIFO present on mobile) from the CPU-side command-buffer build + submit.
