/* ==========================================================================
   Burner Inbox Hub — "ink + ember" theme
   Base ink:      #0E1F33  (deep navy-ink background, as specified)
   Signal blue:   rgb(56,182,255) / #38B6FF (the "new mail" accent — links,
                  focus states, primary buttons: the color of a screen glow)
   Ember:         #FF8A3D (the burn-after-reading accent — sponsored tags,
                  countdowns, the signature "self-destruct" motif)
   Signature element: every provider card has a lit "wick" — a thin ember
   progress bar along its top edge that drains left-to-right, echoing how
   these inboxes expire. It's a real countdown for sponsored listings and
   a static "long-life" bar for the rest, so the motif carries information.
