   ARCHITECTURE: WEBMAIL Layer - The Front Desk's Furniture
   ==================================================================
   STORY:
   QEmail's own standalone webmail chrome — dark, quiet, utilitarian,
   matching the tone of the old status page it replaces (same palette:
   near-black background, sky-blue accent) rather than any one tenant's
   brand. A tenant's own admin console is expected to wrap this in its
   own frame later; this file is QEmail's product, not anyone's skin.
