/* ===========================================================================
   wispa · landing v3 "Ink & Wisp"
   ...........................................................................
   Synthesis of v1 "Noir" (precision dark chassis, violet accent, live demos)
   and v2 "Letterpress" (warm ivory, Fraunces voice, editorial calm).

   Semantics, encoded in tokens and type:
     - serif (Fraunces) + --voice (warm amber)  = the human voice: raw speech,
       quotes, display headlines
     - sans (Inter)                             = the finished text wispa writes
     - mono (JetBrains Mono) + tabular numerals = the machine: keys, meters,
       terminal, model names
     - --accent (wispa violet)                  = wispa acting; the only
       interactive chroma
     - --trust (quiet sage)                     = privacy claims only

   Dark is the DEFAULT (:root). Light ([data-theme="light"]) inherits the warm
   oat paper of v2. Contrast is solved in the token layer: *-text variants are
   AA-safe for small text; --btn-fill is theme-independent under white labels.
