Stacking by game rebuilt a lane's whole array for every row it added, which is
quadratic in the lane's length. That is cheap at three events and not at a
reader with fourteen games switched on and the future plotted — and it is not
paid once, because the board re-renders on every clock tick.
Appending into the array instead is the same output: `Map` preserves insertion
order, so lanes still arrive in the order their first row did and the rows
inside one keep the order they were given, which is what the existing tests
pin.

The focus bar, the settings list, the timeline's lanes and the dailies strip all
go through `orderGames` now, resolved once in App. `games` itself stays in feed
order on purpose: `adoptNewLanes` diffs it and `knownGames` is seeded from it,
so ordering it at source would let a display preference reach the code that
decides which of a reader's games get hidden — a reordering bug would become a
game-silently-switched-off bug.
The dailies strip also groups. It was `[...chores, ...repeating]`, which put
Genshin's commissions and Genshin's own login event at opposite ends with a
dozen games between them; a game's chore and its repeating events are now
adjacent, chore first, events in the order they arrived. Collapsed that is
adjacency alone — no per-game headings, because this is the part of the page
answerable in ten seconds and a heading each would make it the tallest block on
it, pushing "next to expire" down the page.
Two things moved to where they belong. Skipping a standing chore for a lane the
reader invented is `dailyGroups`' rule, not the call site's: filtering those
lanes out in App also cost a reader's own game its place in the order its events
group under. And the expanded catch-up panel is its own exported component, so
which days it offers and whose clock they were cut on are testable rather than
trapped behind a `useState`.
`Welcome` drops its own comparator for the shared rule — the picker runs before
any stored order, so it asks for the A–Z case and cannot drift from the four
surfaces behind it.

`endingSoonestFirst` holds every unstarted event behind every running
one. That is right for a checklist — you cannot do a thing that has not
opened — and it is one answer of two for a board, which is asked what
runs out first. An event opening on Friday and closing on Sunday is a
nearer deadline than one running now until October, and that order can
never show it.
So `byDeadline` is the same comparator with that clause removed, and
`timelineLanes` takes a `split` flag choosing between them. It defaults
to the old behaviour, so nothing moves yet.
The flag is also the one case where lane mode reorders inside a lane,
which the module otherwise refuses to do. Deliberate: the given order is
live-first whatever the reader chose in the list, so honouring it would
draw exactly the block this was asked not to draw.

Lanes keep a game's events adjacent, which is what makes the board
readable for someone playing four of them — but a reader with four games
has one queue of deadlines, and lanes scatter it: the thing ending
tonight sits three lanes below the thing ending next month, and no
amount of scrolling puts them side by side. So the stacking becomes a
choice, and the choice is remembered like the scale and the view are.
The merged mode sorts with endingSoonestFirst rather than a bare end
date, so the timeline and the list cannot mean different things by the
same words — and an unannounced end keeps its place behind every dated
one instead of pretending to a deadline.
