* perf(studio): clicking an element in the preview selects it without restyling the whole film
Every hit test added a `* { pointer-events: auto !important }` style element to the
preview document and removed it again. Each insert and removal restyled every element,
and the head mutation made the off-canvas indicators rebuild their layer walk from
scratch. The override only let pointer-events:none elements into the hit list, and the
author pointer-events filter removed them again, so the hit test now uses the browser's
own result: the candidates are what Chrome itself hit-tests.
* docs(studio): the double-press hit test comment no longer claims it lifts pointer suppression
