/* 1999.LOC — the mail tool's own face: Outlook Express.
 *
 * Third of the per-app identities. Same convention as app-pdf.css and
 * app-zip.css: one stylesheet per tool, loaded only by that tool's page,
 * scoped entirely under [data-app="email"].
 *
 * Outlook Express, as distinct from every other Windows program of the
 * period, was three things:
 *
 *   1. The folder pane. A tree down the left with "Local Folders" at the
 *      top and Inbox, Outbox, Sent Items, Deleted Items, Drafts under it,
 *      each with its own small coloured icon and the unread count in
 *      brackets after the name. Nothing else on the machine looked like it.
 *   2. The blue. Its toolbar and selection blue is #0a246a / #316ac5, not
 *      the grey of the rest of Windows, and the folder pane's header is a
 *      solid band of it.
 *   3. The toolbar. Large icons with their names underneath, like WinZip,
 *      but narrower and with a lighter face.
 *
 * The mail list itself is styled by .mail-client in style.css and is left
 * alone here: it already reads as a message list, and duplicating it would
 * be two places to change one thing.
