The notifications package auto-hides a notification after 5 s only when it
is NOT dismissable. Everything raised through addError/addFatalError is
dismissable, so every error waits for a click forever, at 450 px of pale-red
fill with near-black text over a dark theme — and a fatal one SHAKES, three
times, which is punitive UX with an actual keyframe.

Nothing is lost by hiding them: the same package keeps a timestamped log of
every notification, reachable with notifications:toggle-log. That is what
makes a timeout safe rather than careless — it hides the interruption, not
the information.

notifications.js gives every dismissable notification a life, longer the
worse it is (4 s info to 25 s fatal). Hovering pauses it, because reading is
not dismissing. Clicking cancels it for good, because a click means "I am
working on this". Notifications the package already auto-hides are left
alone: one owner per behaviour.

notifications.less makes the panel dark, translucent and blurred so the code
underneath stays readable, moves the type into the colour of the icon strip
instead of a wall of fill, deletes the shake, and draws a 2 px countdown bar
from the same duration the script used — read through a custom property, so
the bar cannot disagree with the timer. Ship's Bridge tokens, so the editor
and the armada UIs say "error" in the same colour.

They live here rather than in ~/.pulsar so the reasoning is in git; the
dotfiles hold one require and one @import. The stylesheet was compiled
before landing. init.js needs a window reload to take effect; styles.less is
live on save.
