/**
|
|
* dees-tile — the unified "rounded on rounded" tile frame.
|
|
*
|
|
* RESPONSIBILITIES (what this component owns):
|
|
* 1. Outer card — border, border-radius, background, overflow clipping
|
|
* 2. Flex column layout — stacking header / content / footer vertically
|
|
* 3. Content inset — the rounded inner area with border-top and border-bottom
|
|
* 4. Default heading — styled 32px heading text when no slot="header" is provided
|
|
* 5. Footer visibility — auto-hides footer area when slot="footer" is empty
|
|
*
|
|
* NOT RESPONSIBILITIES (what consumer components own):
|
|
* - Header/footer height, padding, font-size, colors when using custom slots
|
|
* - Content layout (absolute, flex, grid — consumer decides)
|
|
* - Any semantic meaning of header/footer content
|
|
*
|
|
* The header and footer slots are BARE containers (just flex-shrink: 0).
|
|
* The slotted content fully controls its own appearance.
|
|
* Only the default heading fallback (.tile-heading) carries tile-level styling.
