/* Production Line Downtime Cost Calculator
   Matches the /tools convention: dark hero, light page, inputs left with a
   sticky results panel right, .ld-outer capped at 1080px. Everything is
   prefixed .ld- so nothing can collide with the theme or another tool.

   Accent is amber rather than the site blue: this tool is about a line being
   stopped, and amber reads as "halted" where blue reads as "informational".
   Amber is used for state, not as a brand colour. */
