/**
|
|
* Pure parser for the `data-start` timing expression grammar, shared by the
|
|
* browser runtime resolver (`createRuntimeStartTimeResolver`) and the Node-side
|
|
* video-frame extractor (`parseVideoElements`) so both agree on exactly what a
|
|
* relative reference means. No DOM/browser dependencies — safe to import in
|
|
* Node.
|
|
*
|
|
* Grammar (matches the docs' "Relative Timing" section):
|
|
* - `"12.5"` -> absolute seconds
|
|
* - `"intro"` -> start when clip `intro` ends
|
|
* - `"intro + 2"` -> 2s after `intro` ends
|
|
* - `"intro - 0.5"` -> 0.5s before `intro` ends (overlap)
