Subject: [PATCH] file viewer panel keyed (445 -> 414)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

VideoRenderer used t as its track loop variable in two maps, so keying the panel
shadowed the translation function — renamed to track. That is the third panel with
this collision; it is worth knowing that a one-letter loop variable is the main
mechanical hazard in this phase.

The useFileViewer context Error stays English: thrown, not rendered.
