Unify stackblitz and github samples

[solenya-group]

Apart from a sprinkling of bootstrap, they're mostly the same, so makes sense to unify them. Ideally they'd be sourced from the same place, as opposed to having to manually copy the samples.

Ideally the StackBlitz samples would have a polished appearance (font, color, layout) as Wood's other samples... because in spite of the adage "don't judge a book by its cover", statistically everyone does.

Agreed.
