/*
 * Shingle color visualizer. One real photo + one roof-shape alpha mask
 * (both generated from a real completed Joe's Roofing job, not stock or
 * manufacturer imagery). mix-blend-mode:color swaps the roof's hue/
 * saturation on click while keeping the photo's real shading and shingle
 * texture -- mask-repeat must be no-repeat and the mask needs a real
 * alpha channel (not just grayscale luminance): -webkit-mask-image (the
 * engine Chromium/Safari actually use) reads alpha only, so a
 * luminance-only PNG renders as if unmasked -- the whole photo tints
 * instead of just the roof.
