There was a problem hiding this comment.
Minimal and correct. Confirmed during triage of #2933 — the commented-out rule was the root cause of the FOUC since Tailwind's .hidden utility has no effect until the CDN/JIT compiler runs. Once Tailwind loads, both rules are display: none (no !important conflict).
Uncommented the .hidden { display: none; } rule in admin.css that was
causing a Flash of Unstyled Content (FOUC) on page load. Until Tailwind
CSS loads via CDN/JIT, the hidden class had no effect, causing all tab
panels to be briefly visible. This was especially noticeable with the
ToolOps panel which has hx-trigger="load" and starts fetching content
immediately.
Closes #2933
