site 1.4.0: Pionaarr Mods -- plainer text, player look, moving background, stock switch

- Hero renamed Pionaarr Mods with a short plain explanation; card texts trimmed.
- New before/after shots: stock against every mod incl. those in testing (3-band waveform).
- Look taken from the player: LCD chip, CDJ-style tabs, Chakra Petch/Barlow, a record
  and a 3-band waveform running in the background (static with reduced motion).
- Builder: Stock firmware switch clears and locks the mods, gives the picks back when off.
