What If Humans Could Photosynthesize: Sunlight, Hunger, and a Body That Feeds Itself

Under a low-iron dome, a midwife peels back a blue glazecloth one notch at a time and a newborn's skin warms to 85,000 lux-the first meal is light. From delivery rooms that ration photons to bus stops timed to the greenhour, the consequences of skin that feeds on sun spill into clinics, kitchens, courts, and roofs.Food moves into the skin: dermoplasts spin glucose beneath shy-olive tones; nurses stage "initiation" like a downbeat; first latch waits; overbloom burns scar careless forearms. Night runs hot by two degrees in the afterlight. Aluminum-filament veils, Saint-Gobain low-iron skylights, and a LuxSense 9 on a chrome gooseneck turn wardrobes and homes into instruments.Public life rewrites the clock and the map. Local Law 30 of 2030-the Public Radiance Guarantee-creates suncourts and light easements; a balcony that stole noon loses to District 35's docket at 642 Sterling Place. Dose is registered by light, not by loud voices: SunQuant Pro over Junior, a ten-percent bias correction for darker kids, library kiosks that take anonymous doseband reads into a block median, and a data trust that writes §12-201 immunity so NYPD can't subpoena the noon line.Work and hunger re-sort. HelioPivot carousels and helioterraces rotate shifts; wintering bus stops slide to a high pass at 12:48; the salt stall sets up under awnings while clinics keep protein in locked fridges; lactation holds a slot on the taped sun chart. When GOES-16 models push a "bad sky" alert and OEM calls Stage 1 Light Emergency, rotation of nothing is still nothing. And when an eclipse crawls across the shared roof and every doseband on the block flashes red, who eats first?
