/* Sitetisfy floating chatbot (Initiative 5 / Sprint 7).
   Self-contained: every rule is prefixed .sfy-cb- and resets what a template's global
   button/input/heading styles could leak in. The widget is a light card on purpose so it reads
   the same on all 33 templates (including the dark ones) — and anywhere else it gets embedded
   (e.g. new-sitetisfy-compro). The widget builds plain HTML tags (section, header, form, strong,
   span) with no attribute marking them as "not part of the page", so a host's generic element
   selector (seen in the wild: `section { padding-block: 6rem }`, which silently padded the whole
   chat panel) wins on any box-model property this stylesheet doesn't explicitly set itself —
   margin/padding/border win by specificity, not by being more "correct", so they must be zeroed
   here for every element this widget creates, not just the ones that currently need it. */
