/*
  shepherd-durakey.css
  Hand-written tour chrome for the Durakey v14.0 onboarding engine.
  Replaces shepherd-theme-default.css (legacy). Bootstrap 5 + CompanyTheme aware.

  CSS variable contract (set from Walkthrough.razor via shepherdInterop.applyTheme):
    --durakey-tour-surface         tooltip background
    --durakey-tour-text            body text
    --durakey-tour-accent          button + focus ring + progress
    --durakey-tour-accent-contrast text on accent (button labels)
    --durakey-tour-focus-ring      keyboard focus outline

  Selector scope: all rules are scoped under `.shepherd-durakey` so Shepherd's
  global stylesheet (if it ever leaks in) does not override. Applied via
  defaultStepOptions.classes in shepherdInterop.js.
