zeekayandHanzo Dev d504ef37b2 Hold the page to one gutter at every width
The responsive section measured itself against a second container. Its
breakpoint ruler rode Container — the docs page's measure and gutter —
nested in the ContainerLarge every other section stands on, so a marker
labelled 500 stood 522px from the mock it measures, and below sm a
hand-fitted translate put the mock 25px left of its own heading, off the
page. Both take the section's own box now.

The preview strip scrolled to an arithmetic copy of its padding and gap
that had drifted from them by one gap per stop, so the ninth colour sat a
whole card off centre. It asks the layout instead.

A stop reaches the swatch, the demo, the ink and the stored accent, never
the ground, and a lamp carried past the hero is the ground by another
route — the wash still under the player row. The glow stays at the hero.

Two footer columns had no basis to size from once stacked and drew over
the next, nine swatches could not fit 390 in one row, and a title glued
to its last word was split mid-word instead.
