Two radiation mechanisms, inverse Compton scattering (ICS) and synchrotronradiation (SR), suffice within the cannonball (CB) model of long gamma raybursts (LGRBs) and X-ray flashes (XRFs) to provide a very simple and accuratedescription of their observed prompt emission and afterglows. Simple as theyare, the two mechanisms and the burst environment generate the rich structureof the light curves at all frequencies and times. This is demonstrated for 33selected Swift LGRBs and XRFs, which are well sampled from early until latetime and faithfully represent the entire diversity of the broad-band lightcurves of Swift LGRBs and XRFs. Their prompt gamma-ray and X-ray emission isdominated by ICS of `glory' light. During their fast decline phase, ICS istaken over by SR, which dominates their broad-band afterglow. The pulse shapeand spectral evolution of the gamma-ray peaks and the early-time X-ray flares,and even the delayed optical `humps' in XRFs, are correctly predicted. The`canonical' and non-canonical X-ray light curves and the chromatic behaviour ofthe broad-band afterglows are well reproduced. In particular, in canonicalX-ray light curves, the initial fast decline and rapid softening of the promptemission, the transition to the plateau phase, the subsequent gradualsteepening of the plateau to an asymptotic power-law decay, and the transitionfrom chromatic to achromatic behaviour of the light curves agrees well withthose predicted by the CB model. The Swift early-time data on XRF 060218 areinconsistent with a black-body emission from a shock break-out through astellar envelope. Instead, they are well described by ICS of glory light by ajet breaking out from SN2006aj.
