make a "minimal" theme

[alixander]

stroke-width 1 for everything, just black and white, no rounding corners, maybe even no bolding

i think that rather than increasing the number of themes, it iwould be better to use "d2-config" to allow also dark themes to be configured.

c.f. like a "minimal" theme

vars: {

it would be good to have a way of writing 'bit flipping'.

vars: {
  d2-config: {
    layout-engine: elk

    theme-overrides: {
      N1: "#000000"
      B1: "#000000"
      B2: "#000000"

      B4: "#ffffff"
      B5: "#ffffff"

      B3: "#ffffff"
      B6: "#ffffff"
      N4: "#ffffff"
      N7: "#ffffff"
      AA4: "#ffffff"
      AA5: "#ffffff"
      AB4: "#ffffff"
      AB5: "#ffffff"

      AA2: "#000000"
      N2: "#000000"
      N5: "#ffffff"
      N6: "#ffffff"
    }

   dark-theme-overrides: {
      N1: "#ffffff"
      B1: "#ffffff"
      B2: "#ffffff"

      B4: "#000000"
      B5: "#000000"

      B3: "#000000"
      B6: "#000000"
      N4: "#000000"
      N7: "#000000"
      AA4: "#000000"
      AA5: "#000000"
      AB4: "#000000"
      AB5: "#000000"

      AA2: "#ffffff"
      N2: "#ffffff"
      N5: "#000000"
      N6: "#000000"
    }
  }
