/*
 * Auth pages (login / register / forgot / new password).
 *
 * Layout is driven by the panel artwork (character + frame), not by a
 * blurred photo + glass card. The artwork is a fixed 1406x709 image;
 * every position below is a percentage measured off that image, so the
 * markup lines up with it at any screen size as long as the container
 * keeps a 1406:709 aspect ratio.
 *
 * Asset: save the panel image as /img/background/auth-panel.png
 * (the copy in this delivery is named auth-panel.png).
 *
 * Note on the title: the artwork you sent has "Log in to your account"
 * baked into the graphic. That's fine for the login/register screens,
 * but "new password" needs its own title, and both need to work in
 * English and Khmer. Two ways to handle it:
 *   1) export one panel per screen/locale with the right title baked in, or
 *   2) export a "clean" panel with no title, and let .auth-heading below
 *      render the real (translatable) title in HTML.
 * This file assumes (2) — it renders a real heading — because it's the
 * only version that doesn't need a new export for every string. If you
 * go with (1) instead, just add a `.auth-heading{ ... sr-only rule }`
 * and keep the image's title as the visible one.
