The base feed now wears the highest ratified era -- sepia film with sprocket holes, phosphor broadcast with interlace, rainbow-on-black disc gloss, the classic SMPTE stream, blinding fortress white. Corruption stays era-agnostic: same shader, same params, only what they are painted onto changes. Boot era is reel, so the world starts in the deepest stratum and climbs to the surface. The old SMPTE look is now mid-game. The chyron generalises from an idle-only placard to a line of text, which is what lets the radio caption the sky in a later commit.
