/* --- A note on the two border tokens (WCAG 1.4.11, non-text contrast) ---
   --color-border is a hairline for decorative rules: table lines, card edges,
   section dividers. It is deliberately faint (1.3:1) and that is fine, because
   nothing is lost if it goes unnoticed.
   --color-field-border is for the boundary of anything a user operates -- text
   inputs, selects, textareas, bordered buttons. Those are user-interface
   components, so their boundary must clear 3:1 against BOTH the fill inside and
   the surface behind, or the control is invisible to low-vision users. Do not
   collapse these two tokens back into one: darkening every hairline to 3:1
   turns the page into a grid, and lightening the field borders hides the forms.
