/*
  Perch VBT import workflow.

  Loaded alongside styles/v3-app-shell.css in v3.html (after it, so the
  --v3-* custom properties it defines are already in scope) -- this file
  never redefines them and never touches css/styles.css, the legacy Phase
  9.7 stylesheet. Scoped entirely under .v3-perch-import-* /
  [data-perch-import-*] selectors so it can never bleed into the rest of the
  shell, the Force Measurement dashboard's .v3-fm-* styles, or the Force
  Measurement import's .v3-import-* styles.

  Unlike the Force Measurement import, this is an inline section of the
  Velocity-Based Training panel rather than a modal overlay -- so there is
  no overlay/backdrop rule here.
