/**
 * The page container every screen roots itself in. Owns the tagged root
 * (`<screenTag>_screen`), the page padding from `PaddingPage`, and that token's
 * inspector self-report — the reported value is derived from the token itself, so it
 * cannot drift from the catalog. Screens never hand-roll their root column.
 *
 * @param screenTag Feature slug ("home"); the root is tagged `<screenTag>_screen`.
 * @param scrollable True wraps the column in a vertical scroll. Leave false when the
 *   content scrolls itself (a `LazyColumn`) — nesting the two crashes at runtime.
 * @param content Column body, laid out inside the page padding.
