Initial commit for the Spearhead blocks, the FSE blocks version of the original Spearhead theme.

A really good version of Spearhead!

There are a few minor differences between Spearhead and Spearhead blocks I've noticed.

Margins for buttons and font size of buttons seems to be a bit different:

Spearhead:

Spearhead Blocks (current):

The page Title size is different and the default font size in the original I believe is a bit larger than what the block version has:

Top padding is higher:

I thought the "dark mode" was one of Spearheads nicest design features. One thing you might want to consider; Instead of including a "dark mode" as an alternative style variation include the "dark colors" in the palette and mapping them with a media query:

@media (prefers-color-scheme: dark) {
  body {
    --wp--preset--color--primary: var(--wp--preset--color--primary-dark);
    --wp--preset--color--secondary: var(--wp--preset--color--secondary-dark);
    --wp--preset--color--foreground: var(--wp--preset--color--foreground-dark);
    --wp--preset--color--background: var(--wp--preset--color--background-dark);
  }
}

Thank you so much for these inputs @pbking. Updating with fixes to those shortly
