The merged markdown-rendering change served /static from a disk directory,
but the live deployment only replaced the binary and templates, so
/static/js/markdown.js and /static/css/markdown.css 404'd and every
article/comment rendered empty (BlogMD was undefined and threw).
- main.go: serve /static from an embedded FS (go:embed) — deployments
now only need to replace the executable; no static dir to copy.
- install_linux.sh: drop the static directory copy (no longer needed).
- article.html / comment_list.html: if BlogMD is unavailable, fall back
to plain (HTML-escaped) text for the article body, comment bodies and
the comment preview, so content is never blank.
- README: document the static/ directory.
Verified locally: /static/* serve 200 even with the disk directory
removed; normal render path (25 checks) and the fallback path both pass.
