/* Design tokens: erp-odoo. Clean business-software look, original and unbranded.
   Palette: cool slate ink on soft grey-white paper, indigo-blue for actions, a green accent for "done" states.
   Deliberately NOT Odoo's colours or artwork.
   Contrast (hand-calculated, AA): ink on paper ~15:1, navy-700 on paper ~9:1, white on navy-700 ~9.5:1,
   success-700 on success-bg ~6:1, error-700 on white ~6.5:1.
   Type: system stacks only, 1.25 scale. Names such as --color-navy-* and --color-safety are kept so the
   shared layout/site CSS resolves; here safety is a soft amber highlight (use as fill, not as text). */
