/* Loupe site v2. World: the maker's own Teto MVs (pink / ink / cyan, the colours of 「うそつきのペルソナ」)
   seen through a loupe. Borrowed mechanisms, Loupe's own content: film strips cross the hero like speed lines
   (P4), timecode tapes cross like KEEP OUT tape (P4), giant vertical timecode (Mika Pikazo), a lens-shaped
   colour plane opens into the next section (Mika Pikazo, seamless), a sticky scroll story (Apple). */
