   SENSO® Cloud – stylesheet (Version 1)
   Based on the toolkit master (00-toolkit/styles/style.css), CI values from
   00-docs/ci-values.md (confirmed by Minna 2026-10-08).
   --------------------------------------------------------------------------
   HOW TO CHANGE THINGS
   All editable values are in section 1 ("Settings"). Change them there only.
   Sizes are plain numbers = pixels on a laptop (1440 px wide).
   Smartphones, tablets and large screens scale automatically.
   Accessibility (Barrierefreiheit): section 4 + checklist section 10.
