/* =========================================================
   Theme — ported from Speechlytics (Overrides.css / Site.css).
   --tmf-primary and --tmf-secondary come from the branding template (_BrandTheme); every shade below is derived
   from them, so a template only sets two colours. Status colours (success, danger, warning) keep Bootstrap's
   defaults: their contrast is what keeps the pages at Lighthouse accessibility 100.
