Gaps in the current rules

• A Tile used with only some of its sub-components (a bare body, no header or footer) is not demonstrated anywhere. The one published story always uses the full header/body/footer composition, so the container’s appearance in a simpler configuration is unconfirmed visually.
• No theme override exists for this component at all. Every visual property is applied inline from generic, cross-component tokens rather than registered against a named component key — unlike every overlay component in this category. Whether that is an intentional difference (this is a structural region, not a themed control) or simply not yet built is unrecorded.
• TileTitle’s text-extraction logic for the tooltip is not exercised by any test against complex nested children. Whether a title built from more than a single text node or simple wrapped element truncates and tooltips correctly is unconfirmed.
• The relationship between this component and Card is not stated anywhere in source or in any design specification found. This page’s own “Choose something else” comparison is derived from reading both components’ code, not from a documented decision that the two are meant to serve different jobs.
