Verified from the live DOM that fusion_plating_portal wraps the app in
#wrapwrap > main > .o_fp_portal_shell > .o_fp_portal_main > #wrap.o_portal_wrap
> .container. The white frame was .o_fp_portal_shell (+ .container max-width),
which my earlier wrapper-neutralisation didn't target. Add the shell + inner
main + force all wrappers transparent/full-width/no-padding under
body:has(.fclk-app). Live on entech 19.0.3.12.4.
