/*
 * Auth screens: sign in, sign up, forgot and reset password.
 *
 * The frame is the LearnBoard instant demo layout, which the owner asked for:
 * a white panel floating over a blurred screenshot of the product, the form in
 * a tinted well on the left, and on the right an eyebrow pill, a display
 * heading, a lede, three points and the compliance framework marquee.
 *
 * The colours are Risenoow's, not LearnBoard's: the product teal, Inter, and
 * both themes, because these pages sit in front of a product that has a dark
 * mode and people arrive from it. The light values are the ones the product
 * uses in light mode, so the page does not change identity at the door.
 *
 * Every class here is one the pages already used (hn-auth-*), so the four
 * pages carry their own fields and handlers exactly as before.
