A road trip tab on the mobile trip screen: the stage as a chain, the same
map underneath it, the sheets a passenger needs, and a search along the
route.
The addon was desktop only because road trip MODE is a data switch rather
than a view switch. It rewrites `assignments` and `places` for the whole
planner hook, and every mobile sheet is permanently mounted and reads those
same two lists, so turning it on there brought back documented regressions.
The mode flag is therefore untouched. A second flag, `roadtripFeedActive`,
feeds only the routing round and does it off the STORED assignments, so the
phone gets the drive without what the mode drags along with it.
The map is one instance shared by the plan tab and the road trip tab,
hoisted into a single JSX expression so React keeps it in the same position
and the WebGL context is never torn down on a tab switch.
The corridor search is scoped to what a phone can afford: a window of the
day rather than all of it, a smaller tile ceiling, a capped retry pass and a
deadline. The standard search is three requests where the desk makes
fifteen. The categories are deliberately not narrowed, because they all ride
one query per box, so a second one costs nothing.
Two gaps found while wiring it up are closed here as well. The fuel search
drew its offers nowhere on the phone, so the button did nothing visible;
they are in the dry band now, with the detour, the spare range and an accept
button. And the map credit opened as a two line ribbon across a screen the
map fills: both GL engines now start it collapsed, and Leaflet, which has no
collapsed mode of its own, is given one.
/trips/:id?tab=finanzplan opens the planner straight on that tab. Read in
the state initializer, not an effect, so the planner never paints the plan
view and swaps a frame later. The param is consumed on arrival; the
session memory keeps the choice across a reload.
Two things the tab machinery got away with while nothing ever started on a
tab other than plan:
- the guard evicted anything not in TRIP_TABS, but enabledAddons is an
optimistic guess until the addon feed answers, and collab is guessed off
- so a requested collab tab was thrown away a render before we knew the
addon was on. It now waits for the feed, like it already did for plugins.
- the lazy loads hang off handleTabChange, which the tab we *start* on
never goes through. Opening on Files showed an empty list, and that was
already true for a tab restored from a previous visit.
Tab ids move to constants/tripTabs so the settings picker can name them
the way the tab bar does instead of keeping a second list.
