What are we casting?
Describe a website. Forge pours it as one self-contained HTML file. Every pour is kept as a heat you can go back to.
Add a section to the current casting. Forge places it where it fits and matches the page's type and colour.
Recreate an existing design as a template, from a screenshot (best) or a URL.
URL cloning asks a public screenshot service (thum.io, then microlink) for an image of the page, so the URL is shared with that service. If both fail, Forge works from the address alone.
Override the casting's colours, type and spacing. Changes show on the casting as you adjust; Apply keeps them as a new heat.

Spacing and shape
Works best on fresh castings: it overrides body, heading, link, button and section styles with !important.
