/* RealFeel Nova - the project's site.
   Palette from the synths themselves: steel drafting paper, ink navy, the MiniNova's panel blue, the LCD's blue and
   its pale glyphs, and the ember / phosphor of the spectrograms (Original = ember, Modern = cool glyph blue).
   Type: Big Shoulders Display (headlines only: condensed, like panel printing), Barlow (reading: close to the DIN
   the synths are labelled in), IBM Plex Mono (figures). The dot-matrix readouts are canvases (lcd.js). */
