/* ==========================================================================
   Theme presets (header "Theme" menu).

   These are whole looks, not palettes: each one rewrites surface, type and
   card treatment together. They are declared after the palette, background and
   text-style blocks so that, at equal specificity, source order lets a preset
   win. "Classic" declares nothing, which leaves the footer's Customize
   appearance controls fully in charge — that panel is unchanged.

   Note --white carries the card surface AND the contrast colour used on top of
   --blue. On dark presets both invert together, so it stays legible.
