   FacultyHack@Gateways 2026 — mobile-first stylesheet
   WCAG 2.2 AA: colors below are verified against their actual backgrounds.

   Brand palette (as given, hand-verified against the backgrounds they're
   actually used on — see notes below, not all 5 are safe for every use):
     Soft Ivory       #FAFAF7  Neutral    → --color-bg
     Root Brown       #6B4A2A  Roots      → --color-text (AAA, ~7.6:1 on Ivory)
     Forest Olive     #55661A  Foundation → --color-link (AA, ~6.1:1 on Ivory)
     Warm Brown/Gold  #876237  Innovation → --color-accent (AA w/ white text, ~5.5:1)
     Olive Green      #6E7D1F  Knowledge  → --color-heading, h1 ONLY (~4.35:1 on
                                Ivory/white — clears the 3:1 large-text minimum
                                with margin, but falls just short of the 4.5:1
                                normal-text minimum, so it's not used for body
                                text, links, or smaller headings like mentor/
                                organizer card names)

   --color-header-bg is Forest Olive (#55661A) and --color-footer-bg is
   Root Brown (#6B4A2A) — two different brand colors, deliberately not the
   same, each its own variable. Both are dark/medium enough that they use
   Ivory text (var(--color-text-inverse)) rather than the body's Root
   Brown text color: Ivory clears ~6.1:1 on Forest Olive and ~7.6:1 on
   Root Brown, comfortably past the 4.5:1 minimum for normal-size text.
   (Olive Green, the other brand green, was NOT used here even though
   it's also "green" — at this size Ivory-on-Olive-Green only reaches
   ~4.35:1, just short of 4.5:1; Olive Green is reserved for page h1s,
   which are large enough that its lower ratio still clears the 3:1
   large-text minimum. See its own note below.)

   Root Brown and Forest Olive (L≈0.082 and L≈0.115) are both too light
   for the main amber focus ring (#B45309, L≈0.159) to clear 3:1 against —
   no single flat color clears 3:1 against both the near-white Ivory body
   AND a medium-dark bar at the same time (the achievable luminance
   windows don't overlap; verified by direct calculation). So header/
   footer links get a context-specific focus override to Ivory instead of
   amber — see ".site-header a:focus-visible, .site-footer a:focus-visible"
   below. The rest of the page keeps the amber ring.

   Note: the focus ring uses #B45309 (accessible amber) rather than a pure
   gold such as #FFD700 — #FFD700 fails the 3:1 non-text-contrast minimum
   (SC 1.4.11) against this site's background (~1.3:1); #B45309 clears 3:1
   against Ivory and white.
