Subject: [PATCH] fix(documents): bump dark-mode timeline bar contrast to
 3.33:1 (#385)

Previous #0d3358 measured 1.44:1 against the dark surface (#011526),
failing WCAG 1.4.11 (Non-text Contrast) for large UI elements.
#3a6e8c clears 3:1 with 3.33:1 while staying in the navy palette.
Closes Leonie's dark-mode contrast finding.
