Mechanical sweep of all .sx sources, plan docs, and tests/expected
snapshots for the sx language rename (s8/s16/s32/s64 -> i8/i16/i32/i64).
Verified: tools/run_tests.sh 23/23.
Note: the ios-sim build has 2 pre-existing 'restart' dot-call errors
from the sx opt-in UFCS change (sx a47ea14) — independent of this
rename (present pre-sweep); migrated in the follow-up commit.
Drop the ':' before captures (for xs (x) / for 0..n (i)); the index
capture becomes the trailing open range (for xs, 0.. (x, i)). 136
headers across 26 files, mechanical.
Five headless tests (banner_layout, hit_test, swipe_commit,
swipe_intent, swipe_reshuffle) also gain a direct
#import "modules/ui/types.sx" — they named Point/Frame through a
transitive import, which bare visibility no longer permits.
Gates: sx build --target ios-sim main.sx links; tools/run_tests.sh
23/23.
Extend the HUD to show the per-level goal (SCORE x / target) alongside
moves. When the model's level_status (P7.1) is won/lost, draw a centered
overlay banner ("YOU WIN!" / "OUT OF MOVES") with a "PLAY AGAIN" restart
button over the dimmed board; the banner appears once any winning/losing
cascade animation settles. Status is read from the model, never recomputed
in the view.
A finished level freezes board-cell input; only the restart button is live.
Its rect is derived from the shared BoardLayout grid (new BannerLayout), so
the hit-test lands exactly on the drawn button. A tap reseeds the same
starting level through board.restart and clears the transient view layers,
returning to a clean in_progress board.
Banner is text + rects only (honours colour/alpha; no draw-time image tint,
issue 0002). New env capture hooks (M3TE_TARGET / M3TE_MOVE_LIMIT /
M3TE_RESTART) force a terminal status / restart for deterministic goldens.
Tests: tests/banner_layout.sx locks the restart button rect <-> hit-test
round-trip headlessly. Goldens p7_win / p7_lose / p7_restart captured on the
iOS simulator.
