The pack's signature element: the frame that reads the visitor's own data back to
them. `--r-frame` on `--surface`, 8px of padding so an inner shell resolves to
`--r-inner` (16 − 8 = 8, which the reference proves on itself), and a grid of
cells whose walls are hairlines at radius 0.

`alarm` is the whole idea. On the reference, 134 rules re-skin this frame dark
when it detects the reader is in incognito — the argument completes itself with no
copy. It is a **state, not a theme**: drive it from what was detected, never from
a preference or a media query. Build the light state first and completely.
