/* ==========================================================================
   HOME — Miti's exchange index
   ==========================================================================
   #tptab.exchange-tabs and .tab-jump*, from Miti's layout.css.

   TWO THINGS ARE NOT CARRIED. Miti's .subtab row switches between its two
   MODULES, LiveTrees and NaturalGoods; this site has no modules, so the row
   is not rendered and its rules could never match. And Miti tints each jump
   card with its module's colour through --tab-jump-tint — one modifier per
   module. This site has a single brand, so there is a single modifier.

   The jump card's artwork is a CSS background rather than an <img>, which is
   Miti's own decision and the reason this works here: a missing file leaves
   the tint and the label intact, where a missing <img> would put a grey
   placeholder over both. This site ships no artwork for them, so they render
   as flat brand tiles — the designed fallback, not a gap.

/* ==========================================================================
   TAB JUMP CARDS  (Exchange landing, under the preview video)
   ==========================================================================
   Four shortcuts into the Buy/Sell tabs at the top of the same page.

   Each card carries its module's colour as the background COLOUR, with the
   artwork layered over it as a background IMAGE. Until the four images exist
   the cards still read correctly — coloured tile, white label — instead of
   collapsing to an empty box.
