/* VOICE: a calm money tool from SnapByte's lab — quiet, exact, premium.
   IDEA: a break-even meter — two cost lines that cross; the crossing is the answer.
   PICTURE: the crossing-lines chart (hero art on landing, live chart on results).
   COLOUR and TYPE: SnapByte ink #001721, cyan→blue→violet gradient as the single accent; Questrial headings, system sans body.
   LAYOUT: one centred column for the wizard, a wider column for results; nothing else on screen. */
