Straighten out French in first paragraph of foreword

I am rereading the French text to appreciate it on its own,
straightening out the sharp angles that make it look translated
rather than said in natural French.
Remove ambiguity of "l'un à côté de l'autre" for "alongside"

There was an apparent contradiction to writing side by side without meeting.
I clarified by replacing with "en parallèle" (in parallel) which keeps
the idea.
Replace en dash with punctuation more common in French

I removed the introducing dash and replaced the colon with a semicolon,
to convey the same idea.
Emphasize call and response with punctuation in first paragraph

I replace periods with semicolons to associate the call and response
written as two separate sentences in English. This is in line with
the changes of punctuation that I just made in the next paragraph.
Translate iterate as "reprenait" instead of "répétait"

This is closer to the musical term of "reprise", for a repeated part.
Translate "inspect" as "examinons" instead of "inspectons"

This is more friendly/scientific, less industrial/military.
Translate sentence as a whole, moving first phrase to the end in French

I restored the emphasis lost in the move by introducing the phrase with
with the demonstrative pronoun 'voici'.
Add comma and repeat preposition "dans" to clarify meaning

The meaning was getting lost after in the stretch of the sentence
after "systèmes".
Start to rework long sentence

I changed my interpretation of this sentence, realizing that "Done well,"
at the very beginning is completed with "Our process will vary" at the
start of the next sentence.

I will join these two sentences by a comma in the French translation,
and move the block for "Done well" closer to avoid this long stretch
where the meaning gets lost.
Replace "remue" with "émeut"

This keeps the idea of moving and feeling, while being more natural.
Replace "ballade" (poem in music) with "balade" (stroll)

The two terms are probably related and often confused.
Make translation more natural: "effort requis pour"
Break long lines in source of the translation

The output is unchanged.

EDIT: after making this change, the logic of the argument appears more
clearly, and is reflected in the current translation. There may be no
need to move the start of the sentence closer to its continuation.
Avoid jargon, adding "qui délimite" to clarify "une ligne à l'interface"
Add "adjacents" back

The word had disappeared, included in the idea conveyed by "interface",
but is now a welcome addition following the more verbose clarification
done just before.
Apply adjective "omniprésent" to both "outil" and "plateforme"
Prepare Acknowledgements for translation
Translate acknowledgments
Remove two commas, redundant in French
