/* DB-TIP site styles: black theme
   Visual direction from the client's references (asli.com: black page, heavy
   headings; boostlingo.com: very large clean headings, whitespace, number
   callouts, one bright call-to-action colour).

   Built for low-vision and screen-reader users first:
   - every text/background pair is above WCAG AAA (7:1); see ratios below
   - large base font in rem units, so browser zoom and text-size settings work
   - thick, always-visible focus outlines
   - layouts reflow to one column at high zoom with no sideways scrolling
   - respects reduced-motion and Windows high-contrast (forced-colors) */
