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.
Scale the combo FX with cascade depth (mv.rounds.len) — the same depth the
cascade SFX (play_cascade) steps up on — so deeper cascades read as more
exciting and land in lockstep with the audio escalation. Purely visual and
self-pruning: no board / score / move state changes, and input stays gated by
BoardAnim.active alone.
- board_fx.sx: add fx_combo_level (mirrors audio's cascade_cue_index clamp:
depth<=1 -> floor, depth>=5 -> ceiling). The +points popup now carries the
cascade depth and grows one font step + lerps gold -> hot-gold per level
(fx_popup_font / fx_popup_color). Every burst of a deep cascade gets a
whole-move depth boost (FX_BURST_DEPTH) on top of the existing per-round bump.
- board_view.sx: render_fx_popups derives styling from depth and tops a combo
with a "COMBO xN" label naming the true cascade depth.
- tests/fx_combo.sx: headless snapshot locking the depth->level/font table and
asserting fx_combo_level matches the cascade-cue index column entry-for-entry.
- goldens/p11_combo_deep.png + README: deterministic depth-5 capture (M3TE_FX=11)
vs the depth-1 single clear (M3TE_FX=3); FX gone after settle at a later phase.
