Native basis

CSS Grid (1fr auto 1fr) with a stretch divider column that only appears at container width ≥ 48rem - below it the stack provides the break, so the markup never swaps separators.

§Default

Two large features + four benefit cards.

§Bento grid

.mk-features-bento: tiles of different sizes in a dense grid - data-span='wide' takes two columns, 'tall' two rows, data-tone='primary' makes an accent tile; tiles can end in an image.

§Alternating rows

.mk-feature-rows: zig-zag rows - media and copy swap sides every other row (from 44rem), each with a .mk-feature-checks list of benefits.

§Feature tabs

.mk-features-tabs: the Tabs component as a feature tour - the triggers are the feature list (title + description), the panel shows each one. Arrow keys move between them.

§Boxed cards

data-variant='boxed' on .mk-feature-cards: the benefit cards on surfaces, the icon in a tinted tile, lifting on hover.
