nx_nishi_font.nx

nx_nishi_font.nx -- the SYSCALL-backed u8/PNG path of the sovereign Nishi stroke font. The PURE glyph core (all stroke designs N I S H B R O W E + 0-9 + the WASM-safe i64-framebuffer blit) now lives in the import-free nx_nishi_font_core.nx; this file adds nf_render_glyph (black AA ink onto a WHITE RGB u8 buffer, allocates its own supersample mask via sys_mmap) + nf_draw_text (u8 string), used by the demo + the gate. Splitting the pure core out lets the browser arcade (nx_wasm_arcade) reuse the EXACT glyphs with no syscalls. All integer (no float). license_tier: ORIGINAL
