/* Chronospride Watch Size Calculator.
   Design language: an instrument reading, not a dashboard of stat cards —
   the lug-to-lug figure is bracketed like a caliper measurement (⊢ 47.6mm ⊣)
   because that's literally what the number represents: a span between two
   points. Serif tabular figures for readouts, brass accent pulled from
   watch-case metal rather than the site's default gray-brown. */
