About this question
I have a Lightning Web Component template with a lightning-card in an App Page.
I would like to nest more cards into it to simulate the related list look and feel from standard Lightning experience.
If I add the slds-card_boundary class to the child, it draws a misplaced vertical border fragment above and below the card.
However, if I add the slds-card_boundary class to the article element spawned by the child lightning-card component, the border is correctly drawn around the entire card. Adding a slds-m-around_small to article element also forces a separation between parent and child cards.
What layout concepts am I missing with Lightning Web Components to be able to successfully use lightning-border card components?
In general, how can lightning-border cards be used inside Lightning Web Components to achieve a related list-like appearance?
