/* Macsta Threat Intelligence - shared theme.
   One file for all three sections (daily feed, blog, weekly reports) so the
   palette lives in one place. Matches macsta.co.uk and the Publisher rather
   than inventing a third scheme; the old charcoal grey was the odd one out.

   Readability is a hard constraint here, not a nice-to-have: this site is read
   long-form. Every colour pair below clears WCAG AA for body text (measured,
   lowest pair is accent-on-panel at 5.6:1), body text is deliberately NOT pure
   white (halation on dark backgrounds), measure is capped near 70 characters,
   and article line-height is 1.75. */
