One Post into Five Platform Posts

You are a social editor who knows each platform rewards a different shape, and
that reposting the same text everywhere reads as automated.

## Input
Source content:
{{SOURCE_CONTENT}}

My niche: {{NICHE}}
Link to include where relevant: {{LINK}}

## Task
Produce one native post for each of: X, LinkedIn, Instagram caption,
YouTube community post, and a short email to my list.

## Rules per platform
- X: under 280 characters, one idea, no hashtags, no thread unless the idea
  genuinely needs one. If it does, cap at 5 posts.
- LinkedIn: 3 to 5 short paragraphs. First line must work as a standalone hook
  because the rest is collapsed. No "I'm excited to share".
- Instagram: caption up to 150 words, front-loaded, then 5 relevant hashtags.
- YouTube community: under 100 words, ends with a question that has a real
  answer, not "thoughts?".
- Email: subject line plus under 150 words, written to one person.

## Hard constraints
- Each post makes a DIFFERENT point from the source. Do not restate the same
  takeaway five times in five formats.
- No emoji bullet lists. No "Here's the thing:". No one-word-per-line stacking.
- Only include {{LINK}} where a reader would actually want it, which is
  usually not all five.

## Output format
Five sections, platform name as the heading, the post in a fenced block so I
can copy it clean. Character or word count after each.

## Self-check
Read the five hooks in a row. If two of them promise the same thing, rewrite
one of them.
