/*
 * "Through the Garden Window": layout for the anonymous welcome page and the
 * login page, which are ONE document (account/login.html) with two panels.
 * The page switches panels client-side; .gw[data-gw] says which one shows.
 *
 * The decorative garden canvas (public_wizard/_canvas.html) fills the page
 * and a warm paper sheet holds the content.
 *
 * Desktop (>=960px, the wizard and signup breakpoint): the scene is fixed and
 * full-bleed, the sheet floats at the left (anchored bottom on welcome,
 * centred on login).
 * Mobile: normal document flow on purpose, never a fixed sheet, so the iOS
 * keyboard and page scrolling behave. The garden is a band at the top and the
 * sheet follows it with rounded top corners, overlapping the band slightly.
 * Welcome gives the garden every pixel above the sheet; login keeps a short
 * band (--gw-band) so the form fits.
 *
 * Markup:
 *   .gw[data-gw="welcome"|"login"]
 *     .gw-scene      > the canvas include
 *     .gw-top        > .wz-wordmark + the inline public toolbar
 *     .gw-dock       > .gw-sheet > .gw-panel[data-gw-panel] x2
 *
 * Switching panels (script in account/login.html): on mobile the band height
 * animates (the canvas is sized in container units, so the plants scale
 * with it) while the panels cross-fade; on desktop a same-document View
 * Transition morphs the card (lt-sheet). Reduced motion switches instantly.
 *
 * Colours come from the app's design tokens (app.css), which already switch
 * for html.dark and for the OS dark preference when html is not .light.
 *
 * The signup page (account/signup.html) borrows the phone layout: it keeps
 * the wizard's split layout (app.css) on desktop, and below 960px its
 * .wz-app.gw-phone takes the same band and sheet (see "Signup on phones").
