feat(theme): five themes, and a picker that shows them
Release / Build and publish image (push) Failing after 9m58s

Two themes and a toggle between them. Now five, chosen from a grid under
Settings → Konto: the two that existed, a warm dark (Skumring) with amber
where the green was, a warm light (Papir), and a high-contrast one.

Each swatch is painted in its own theme rather than described, so the
choice is made by looking. data-theme sits on the swatch and not on the
card — it redefines --ink too, and a card wearing a dark theme's ink on a
light page has a name nobody can read.

Every theme states its full palette rather than inheriting and patching.
A partial theme looks finished until somebody adds a token, at which
point four themes silently fall back to a colour from a fifth. That is
also why the dark palette is repeated under [data-theme='dark']: :root
carries it as the default and :root only ever matches <html>, so a swatch
asking for it by name would otherwise show whatever the page was wearing.

The theme-color meta is updated too, so an installed PWA's frame and a
phone's address bar follow rather than staying whichever colour shipped
in the markup.

Contrast measured for all five. The new ones clear 4.5:1 down to the
quietest tier — which is where dates and counts live, and the first thing
to disappear. Kontrast reaches 8.9:1 there. The two original themes are
left as they are: their faint ink sits at 3.1–3.8, which is worth
revisiting, but not as a side effect of adding colours.
