/*
    VisionSO2Web - mobile-first stylesheet.

    Sizing rules that matter on a phone in the field:
      - every tappable target is at least 44px tall (glove-friendly, matches platform guidance)
      - inputs use 16px font, below which iOS Safari zooms the viewport on focus
      - the layout is single-column up to 640px and centres in a readable column above that,
        so a tablet does not stretch text to the full width
