/* ---------------------------------------------------------------
   Benmax Device Setup — design tokens

   Color   #1522af  brand blue     (from the Benmax logomark)
           #0c1868  deep navy      (headings, high-emphasis text)
           #eef0fb  tint           (card fields, subtle surfaces)
           #f6f7fd  canvas         (page background)
           #1f9d6c  confirm green  (decommission / success accent)
           #64698a  muted          (secondary text)
           #d4482f  error red

   Type    Manrope   — headings, buttons (geometric, matches the
                        squared-off diamond marks in the logo)
           Inter     — body copy, form fields (legible small, outdoors)

   Signature: the two rotated, cut-corner squares from the Benmax
   mark, echoed faintly as a background motif and as the loading
   glyph — the page always has a quiet trace of the logo's own shape
   language rather than a generic spinner or gradient.
