/* CaptionLab — shared styles for SEO landing pages (landing_v4/)
   Same design language as the main site (captionlab_landing_v3.html):
   dark theme, cyan accent, Space Grotesk body / JetBrains Mono labels /
   Archivo Black display numerals. Kept as one shared stylesheet (unlike the
   main page's inline styles) since these are simple, mostly-static pages —
   easier to keep the whole cluster visually consistent from one file. */
