// Manual care page: user directly picks a care function (-> single light
// wavelength), regions and duration, then starts — skipping the smart scan.
//
// Care function -> wavelength (protocol WAVELENGTH: IR=1, R=2, UV=3, Y=4).
// SINGLE light per session: buildVendorCommand only lights one wavelength.
// FUTURE EXTENSION: a composite/multi-light care mode would require the vendor
// command builder to accept several wavelengths at once — not implemented here.
