> h2. Problem
> The Apache Flink website ([https://flink.apache.org/]) is nearly unreadable
> in dark mode (prefers-color-scheme: dark). Specifically:
> * The "Flink Capabilities" section: headings and body text (e.g.
> "Exactly-once state consistency") are dark gray on a near-black background,
> barely visible
> * The "Use Cases" section has the same issue
> * Blog card text also has severely reduced contrast
> The website was still displaying correctly as of March 15, 2026 ([Web Archive
> snapshot|https://web.archive.org/web/20260315191034/https://flink.apache.org/]).
> h2. Root Cause
> Commit {{6bdf6191e}} ("Add FlinkCDC v3.6.0 and Rebuild website") used a
> locally installed Hugo 0.159.0 to build the site, but {{docker-build.sh}}
> pins Hugo 0.124.1. Hugo 0.159.0 produces different SCSS compilation output,
> breaking the dark mode CSS.
> h2. Fix
> # Rebuild the website with Hugo 0.124.1 using {{build.sh build}}
> # Add Hugo version check to {{build.sh}} — extract {{REQUIRED_HUGO_VERSION}}
> to {{_utils.sh}} as single source of truth, both {{build.sh}} and
> {{docker-build.sh}} reference it
