* docs: light mode in the studio app's palette
Light mode takes the Studio app light palette (packages/desktop index.css)
instead of the hyperframes.dev beige ground: paper, cards, ink levels and
the light accent ink for links. Plain code text uses the page ink.
Dark mode (Night) is unchanged.
* docs(examples): film rows move by hand and remix shelves stack
The Inspiration film rows drift by a script, as on the homepage
(HyperFramesShowcase): drag, a sideways swipe or shift+wheel moves a row,
and keyboard focus centres a card. Remix shelves are columns that each
stack their cards, so cards of different shapes leave no holes.
