/* MIDI Conductor site. Layout: one centred 1120px frame; overview is a product tour (hero shot, alternating
   screen/text rows, spec sheet, four-step start); manual is a sticky contents rail beside a 720px reading column.
   Look: studio hardware. Graphite panels, the SP's OLED screens shown in a machined bezel, keys drawn as rubber
   pads, one warm accent taken from the SP's lit pads. */
