The device console is a default-grey tkinter window with no hierarchy: no
grouping, no state colour, no type scale, the privilege warning buried in a
monospace paragraph, "Çık" duplicated at two sizes, and an output area that
looks editable. Every measurement is in the delivered work; the point here is
that the fix is a system, not a repaint.
Adds PRODUCT.md (product truth: who uses this, from where, under what
constraints), docs/DESIGN.md (the direction contract and the shared status
vocabulary) and web/static/tokens.css (the values both surfaces read).
The vocabulary is the load-bearing part. Four severities -- ok / warn / danger /
info -- plus one action accent, and one Turkish word per device stage
(KURULDU / KAYITLI / HAZIR / HATA / YOK) used identically on the device and in
the central panel. A fifth hue is a bug, and colour is never the only carrier:
every badge ships its word, so the fleet list stays readable in greyscale.
The ground is light on purpose. The console runs in workshops and dealer service
areas in daylight; a near-black ops console loses its own body text there and its
state colours collapse into equal-brightness smudges.
No webfont: the fleet installs offline from a committed pool, so a font CDN is a
broken page on every device.
