   Previously this file carried the original teal/amber palette
   (--teal:#1A9E8F, --gold:#F0A500) and was not linked by any
   page — every page inlined its own copy. As of this revision
   it is the single source of truth for shared components and
   is loaded by all five pages. Page-unique styling (homepage
   hero, splash, service cards; per-page calculator layouts)
   remains in each page's own <style> block.
