Docs should indicate that `_reboot.scss` uses the variables, but to see their values users would look in `_variables.scss`.
Bootstrap sets basic global display, typography, and link styles. Specifically, we:
-- Set `background-color: #fff;` on the `<body>`
+- Use `$body-bg` to set a `background-color` on the `<body>` (`#fff` by default)
- Use the `$font-family-base`, `$font-size-base`, and `$line-height-base` attributes as our typographic base
- Set the global link color via `$link-color` and apply link underlines only on `:hover`
-These styles can be found within `_reboot.scss`.
+These styles can be found within `_reboot.scss`, and the global variables are defined in `_variables.scss`.
