v0.2.4

The mobile-surface release (M14): the game now uses the screen it is given.
Until now the 420x640 logical playfield was both the box everything was laid
out in and the box the renderer clipped to, so on a tall phone it sat
centred inside the letterbox colour — 377 dead pixels above it and 377 below
it at 1080x2400, with the footers parked in the middle of the glass. The
surface is now elastic: the scale is still the uniform min(w/420, h/640) and
nothing is ever stretched, but the logical band the game draws in grows and
shrinks with the device, and it ends on the physical bottom edge where the
navigation is pinned. The hub also gains its fifth section, Goals.

Added

• An elastic layout surface (M14): ui/layout/LayoutMetrics turns the
  real viewport into a safe viewport and then into the bands a screen lays out
  against — a header region, a flexible content region and the persistent
  bottom navigation — with contentTop(), contentBottom(), navTop() and
  aboveNavHeight(), clamped so the content region never falls under 480 rows
  and the navigation never overlaps the header. Every hub screen re-derives its
  bands when the metrics change, and at the classic 420x640 surface every band
  lands on exactly the constant it replaced.
• Safe-area support (M14): Android reports systemBars ∪ cutout ∪ gestures
  through MainActivity and AndroidHost into the screen stack, so a gesture
  bar or a notch lifts the navigation off the glass instead of under it.
• The Goals section (M14) as the hub's fifth tab, in the Shop/Birds/Play/
  Forge language, with the five-item navigation and Goals on the gold plate
  and no redundant Back button. Challenges is a carousel of cards with the
  world, tier, rules, progress, reward and unlock a challenge actually carries,
  and a gold call to action that starts it. Achievements is a scrolling list
  under a live summary, each card with its name, description and the real date
  it was unlocked. Milestones is a heading, the level bar and one row per
  metric, with current, target and remaining. Collections is eight rows of
  owned / total (percent) plus an Everything card. Every number comes from
  the profile or from the shipped content — the collection totals are computed
  at runtime, so they cannot disagree with the JSON — and the tabs speak en
  and pt_BR through sixteen new string keys.

Changed

• The world picker, the run summary, the statistics and the settings no longer
  anchor their footers to a fixed Playfield.HEIGHT - N. They anchor to the
  bottom of the elastic band, and the room a tall screen frees goes to the
  scrolling region instead of to dead letterbox.
• On a tall screen the world cards grow to fill the list and the run summary
  spreads its rows, rather than one gap growing.

Fixed

• The statistics screen drew the long prestige value right-aligned past the
  panel border — 471 pixels of text in a 372-pixel column, starting at x = −75
  and overprinting its own label. It now wraps on a word boundary inside the
  row's inner margin.
• GoalsScreen did not invalidate its layout when the navigation's top moved,
  and the Forge, the bird selection and Goals each compared only two
  coordinates when deciding whether their metrics had changed, which could
  leave cached hit targets stale. All three now compare the whole value.
