Phase one is near-pixel-perfect reproduction at the comp's breakpoint,
with exactly three concessions (closest font, icons unless a library
was chosen, genuine comp defects); the overlap comparison is the
authority because models systematically believe their code recreation
succeeded when it did not, and regions that keep losing the comparison
ship as composited rendered assets instead. Phase two brings the
reproduction to life (interaction, motion, responsiveness), and
anything beyond the comp inherits the recorded system, never invented
container chrome.
