/* Section 3 — the Artist EQ console.
 *
 * Written by hand for the same reason as the header and the hero: the
 * Tailwind build is checked in, and this needs exact values. The console
 * is CSS over native controls, not an image - it reflows instead of
 * scaling to mush, and the range inputs keep their keyboard behaviour.
 *
 * Materials: dark machined metal, a brushed fader cap, shallow engraved
 * marks, one warm lamp per channel. Nothing is scratched, dusty or
 * artificially aged - the instrument is meant to read as expensive and
 * in use, not as salvage.
