Set the original colour scheme's typeface and palette to the 1987
Docklands Light Railway P86/P89 stock.
- Use the Rockwell slab serif (the original DLR branding typeface) for the
original theme, with Rokkitt loaded as a free fallback for systems
without Rockwell installed.
- Flip the palette to be blue-dominant: blue body/skirt as the field, red
band/doors as the accent, white stripes, matching the rolling stock.
