Write a foreword for a report in a leader's voice

Write a foreword for {{report}} in the voice of {{leader}}, from their notes and past writing below, for the leader to edit and approve. A foreword is often the only page some readers finish, so it should tell them why the report matters now, what to read first and who deserves thanks, in a way that sounds as if the leader wrote it personally, so that it reads as a real introduction rather than a formality.

The leader's notes or talking points for this foreword:
"""
{{leader_notes}}
"""

Samples of the leader's past writing (letters, speeches, posts), for voice:
"""
{{writing_samples}}
"""

What the report is, who it is for and its main findings or contents: {{report_summary}}
People, teams or partners to thank, and for what: {{thanks}}
Length: {{length}}

Structure:
1. An opening that says, in the leader's terms, why this report matters now, drawn from their notes.
2. Two or three sentences on what the report covers and its most important finding, matching the report summary exactly.
3. A pointer to what to read first, depending on the reader, for example "If you read one chapter, read chapter 3 on [topic]." That example shows the form only.
4. Thanks that are specific about what each person or group contributed.
5. A short closing line, then the leader's name and title.

Keep to {{length}}; if none is given, 250 to 400 words. The voice should match the samples: their sentence length, their level of formality, how they address readers and the words they use often. Write in the first person.

Do not add opinions, commitments, figures or personal stories that are not in the notes, the samples or the report summary, because the leader will be held to every word. Do not overstate the findings or promise action the leader has not committed to. Avoid stock foreword phrases such as "I am proud to present" unless the samples show the leader uses them. If the notes do not say why the report matters or what the leader wants to stress, write [LEADER TO ADD: what] in that spot rather than inventing a view. Put a first line above the draft: "Draft for [leader]'s review and approval."
