Here's a minimal example of what I'm talking about.

I would like the Abstract to not start until it will be clear of the
logo graphic on the right side.

In the real document, I cannot be sure how much vertical space will
taken up by text items (Authors, subtitle, etc.) between the Title and
the Abstract, hence my question.

Maybe I am thinking about this in the wrong way and there is a
different approach? I have more of a DTP background.

%%---start example -----------------------%%

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% PAGE LAYOUT
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\setuppapersize[letter][letter]

\setuplayout
  [width=middle,
  backspace=15mm,
  topspace=10mm,
  height=254mm,
  header=5mm,
  headerdistance=3mm,
  footer=5mm,
  footerdistance=3mm,
  grid=yes]

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%% LOGO ON FIRST PAGE:
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\useexternalfigure[logo][dummy][type=pdf,width=35mm,height=50mm]

\definelayer
  [logo-layer]
  [width=\paperwidth,height=\paperheight]

\setlayer
  [logo-layer]
  [preset=righttop,hoffset=15mm,voffset=10mm]
  {\externalfigure[logo]}

\setupbackgrounds[page][background={logo-layer}]

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% HEADS
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\setuphead[title]
 [header=high,
  footer=high,
  grid={page},
  width=140mm,
  textstyle=\tfc\ss\bf]

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% ARTICLE ABSTRACT
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%

\definedescription[Abstract][%
  location=serried,
  width=broad,
  text={Abstract},
  indentnext=no]%,

%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%% ARTICLE TEXT
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\starttext

\title{The title of this article wraps at 140 mm so it doesn't hit the logo}

% A VARIABLE NUMBER OF TEXT ITEMS WILL BE PLACED HERE...

% \godown[3cm] % UNCOMMENT TO FORCE THE ABSTRACT BELOW THE LOGO

\startAbstract
But the abstract can continue all the way across the page...\input tufte\par
\stopAbstract

\stoptext
