ATTR-003: wrong kind of value

Error: the page doesn't build until this is fixed.

Hypra's own settings take one kind of value: priority and decorative are true or false, width is a number. A string like "yes" would mean something different to every reader, so it isn't accepted.

Fails

page(title: "Shoes", description: "All our running shoes, from light racers to trail shoes.") {
  h1 "Shoes"
  img("/img/runner-x.jpg", alt: "Runner X in blue, side view", priority: "yes")
}

error[ATTR-003]: expected true or false, without data

Fixed

page(title: "Shoes", description: "All our running shoes, from light racers to trail shoes.") {
  h1 "Shoes"
  img("/img/runner-x.jpg", alt: "Runner X in blue, side view", priority: true)
}

Settings like priority are also fixed when the page compiles, so they can't come from data.
