Dark mode: `dark:` as a CLASS, not a media query.

---------------------------------------------------------------------------
|

Tailwind's built-in dark variant follows the operating system. A site with its own
|
||
theme switch cannot use it: the OS says one thing, the switch says another, and the
|
||
media query wins — so the switch appears to do nothing.
|
||
|
||
This redefines it against a class on <html>, which webui.Theme toggles. The OS is
|
||
still respected: it is the DEFAULT (see the boot script in server/main.go), just no
|
||
longer the last word.

/* ---------------------------------------------------------------------------
|
||
The wordmark's logo tile: a muted Norwegian flag.
|
||
---------------------------------------------------------------------------
|
||
kjøl is a Norwegian word — the mark says so. It is the flag's Scandinavian cross: a
|
||
navy cross with an off-white outline on a red field, offset LEFT as the real flag is
|
||
(the vertical bar sits at ~38% rather than centre). Muted, not the flag's full
|
||
saturation — it is a 32px tile next to body text, not a banner.
|
||
|
||
Drawn in layered gradients over a red base rather than as an <img>, so it inherits the
|
||
tile's rounded corners and border, needs no asset request, and cannot 404. Layers paint
|
||
TOP-first, so the reading is: dim scrim, then navy cross, off-white cross, red field. Each
|
||
band is transparent outside its stripe (hard stops via doubled positions) so the layer
|
||
beneath shows through. The bands are constant across light and dark — a flag does not
|
||
change with the page theme.
|
||
|
||
The topmost layer is a flat dark scrim, and it is there so the WHITE sailboat on top of
|
||
the tile reads on its own — no outline, no shadow on the glyph. The boat is a thin white
|
||
stroke and the off-white cross is exactly the band it would vanish into; rather than trace
|
||
the boat in shadow, the whole flag is dimmed until white stands out against every band of
|
||
it, the pale cross included. A dimmer, moodier flag with a crisp white boat, on purpose.
|
||
|
||
The cross geometry, as percentages of the tile:
|
||
vertical (offset left, centre 38%): off-white 27–49%, navy 32.5–43.5%
|
||
horizontal (centred, centre 50%): off-white 39–61%, navy 44.5–55.5% */
