nx_browser_importprobe.nx

nx_browser_importprobe.nx -- BISECTION INSTRUMENT for the nx_browser build failure. nx_browser fails on the NAS with "nx_parse: unexpected operator token kind=46 at expression start" (TK_EQ, per nx_lex_kinds.nx:107) immediately after br_comp_border registers -- i.e. inside br_draw. The SAME file bytes (sha 3504e69e) parse br_draw fine on the laptop, whose import closure DIVERGES, so the fault is CLOSURE-DEPENDENT rather than a plain syntax error in nx_browser.nx. This probe carries nx_browser's EXACT import list and nothing else, so it answers one question mechanically ON THIS TREE: builds -> the closure is clean here, the fault is in nx_browser.nx's own body fails -> the fault is in an import, and the error localises it there license_tier: ORIGINAL
