Water Ford adds terrain tiles for Factorio 2.1: a ford you can walk
across, the matching Wooden Flooring for dry land — and the
Cobblestone pair: a road ford vehicles actually drive across, plus
the Cobblestone Path for dry land. The wooden pair keeps footpaths over
the water; the cobble pair opens it to traffic.

Wooden Ford

• Cross water on foot — ford rivers, lakes and your Cargo Ships
  waterways. Biters and Pyanodon's land caravans wade it too.
• Cargo Ships vessels still sail over it and fish swim across the deck:
  the crossing keeps the water navigable.
• Vehicles keep out: cars and tanks are stopped at the shore, so a ford
  stays a footpath. For drivable crossings, that's the Cobblestone Ford
  below.
• The deck lies under animated water, with wooden pilings standing
  semi-submerged at the rims and ballast stones tinting at the waterline:
  a real shallow crossing, not a floating walkway.
• Water stays water: placeable on water only, and fish and other
  water-dwellers treat it as water. Offshore pumps can no longer be placed
  on it.
• Unbuildable: a ford is a crossing, not landfill — you can't construct
  buildings on it.

Wooden Flooring

• Honey-toned plank boards for camps, yards and walkways — land only.
• A raised wooden bumper edge at the waterline and a wooden trim
  against other terrain, so board edges read as built, not cut.
• Same boards, same palette as the ford deck — the two tiles read as one
  family.

Cobblestone Ford

• Drive the crossing: cars and tanks roll straight over, so the
  outposts on the far bank are a road trip, not a bridge-building project.
• Walkers stop at the shore: you and your enemies alike. The road is
  yours — biters can't use it to walk into your base.
• Hand-laid cobbles rise through the water: crowns breach the surface,
  the joints below read submerged — a road that wades, not a floating
  platform.
• Ships still sail over it, and the deck stays water to everything
  else: no offshore pumps, no buildings, placeable on water only.

Cobblestone Path

• Pave roads and yards in grey-blue cobbles that read as one family
  with the ford's deck.
• Land only: paving won't go over water — for a crossing, use the
  Cobblestone Ford.

Works standalone; with Pyanodon's Alien Life all four tiles join the
wood/stone chains and the caravans get their crossings.
