Comments get a Translate button that calls the active LLM provider in Admin → AI
settings. Each commenter shows a small country flag inferred from their
video_views + profile_visits history (falls back to users.nationality); that
inferred country drives the language hint passed to the LLM so Portuguese
"Linda, linda, linda" translates to "Beautiful" instead of pass-through.
Description boxes get a line-paired translation grid: a shared Translate button
flips #vdbDescSplit into a two-column CSS grid where every source line sits
next to its translation on the same row. Backend splits by newline and asks
the LLM for a JSON map keyed by index so counts always match.
LlmLyricsService now has translate() + translateLines() with echo-retry (if the
model returns the input unchanged while source != target, retry once with a
stronger directive) and keeps the Ollama model resident via keep_alive=1h.
