Rules that matter most
----------------------

- Never put the blue logo on black (contrast 1.41:1).
- Keep clear space of at least 2m around the logo (about 2/3 of the P's width).
- Smallest lockup on screen: a 24px-tall P. Below a 32px P, use the
  pixel-aligned PNGs in Icons rather than shrinking the SVG.
- Do not stretch, rotate, recolour single pixels, round the pixels, fill the
  gaps, retype the wordmark, or add gradients, shadows, outlines or glows.
- CMYK values are conversions for reference; proof before printing.
