/* Procurement RFQ — Signisys theme.
 *
 * Palette from signisys.com's own CSS variables: orange #FE6000 (--or), text
 * orange #CF5000 (--or-txt), deep orange #B84200 (--or-d), amber #FEA300,
 * navy #141425 (--nv) / #1E1E36 (--nv2), slate #636380 (--sl), silver
 * #DDDDE8 (--sv). Inter, as on their site.
 *
 * Contrast: white on #FE6000 is 3.05:1 (fails WCAG AA for text), so the bright
 * orange is used for accents only; buttons and links use #D65400→#B84200
 * (4.2–5.5:1, bold text) and #B84200 (5.5:1).
