Neutrino — chiral, neutral, flavour-oscillating

Reading it (SCHEMATIC). The packet is neutral — there is deliberately no flux collar and no illuminated EM faces; that absence is the fingerprint. Its chirality helix is left-only (no C-flip). The flavour content beats between three states — shown as a shifting tint plus a three-bar meter and a hatch whose spacing oscillates, so it reads without colour. The decoupled right-handed ν_R is drawn as a faint dashed zero-syndrome vertex, present but disconnected.
