fix: cache-bust style.css per build (deploys picked up immediately)#76
Merged
Conversation
The stylesheet <link> had no version string, so browsers cached it for
max-age=600 (10 min) — after a deploy users kept seeing the old CSS until
the cache expired. Append ?v={{ site.time | date '%s' }} (build timestamp)
so every deploy yields a fresh URL and the new CSS loads immediately.

Problem
After merging a CSS change and waiting for Actions to finish, the live site kept showing the old styling. Verified the cause: the origin was serving the new CSS (
last-modifiedmatched the merge, new markers present, old gone), but the stylesheet<link>carried no version string and is sent withcache-control: max-age=600. So browsers reuse the cachedstyle.cssfor up to 10 minutes after every deploy.Fix
Append a per-build version to the stylesheet URL:
href="{{ '/assets/css/style.css' | relative_url }}?v={{ site.time | date: '%s' }}"site.timeis the Jekyll build timestamp, so every deploy produces a fresh URL (style.css?v=<ts>) and browsers fetch the new CSS immediately instead of waiting out the cache.Verification
Build clean (exit 0); compiled
<link>carries?v=<timestamp>on the home page and guide pages (layout-wide). One-line change in_layouts/default.html.
