v0.1 — "Lights on"

The Neon theme features three rows:

1. the first one hosting "secondary" information, in blue (jobs,
   sensors, dev context, etc.),
2. the second row displays "primary" information (user, path, VCS,
   etc.), in green,
3. the third one is dedicated to the prompt (runtime, error code,
   prompt mark), in cyan.

Within each row, important notice are displayed in bold (and thus
probably in a slightly lighter color, depending on your terminal
configuration).
