32-bit word access is indexing now, not peek32/poke32:
peek32(ui_rx, i) -> ui_rx[i] (reads an int)
poke32(rt_fb, i, c) -> rt_fb[i] = c (writes an int)
A buffer typed `words` (a pointer whose elements are i32) indexes with `w[i]`
as a full int; a plain `ptr`/`str` keeps byte indexing. emit_index_addr picks the
element type from the base's type — byte-identical IR to the old intrinsics, so
the migration reproduces the compiler and every golden render exactly.
The ~60 word buffers (rt_fb, tt_*/gc_* font tables, png_px/spr_px pixels, ui_*
layout arrays) were retyped from `ptr` to `words` scope-aware (per-function, so
the s/out/p byte-vs-word name collisions across functions stay correct), then the
254 peek32/poke32 sites migrated to indexing. A scope-analysis miss left 12
buffers (gc_*, sc_d, ui_rx/ui_ry) un-retyped — caught as a menu golden diff and
fixed. No true mixed byte+word access exists on any one variable, so a per-buffer
element type is sound.
Reseeded (22527 lines); C-free fixpoint holds; goldens byte-identical; 18/18;
vocab (byte/words types in, peek32/poke32 out) + doc-fences clean.
