Generate a Realistic Morning Routine Around a Fixed Wake Time

Every morning routine you find online assumes ninety minutes and a garden to meditate in. This works from your actual wake time and the time you need to leave, fits your genuine non-negotiables first, and only adds anything extra if the maths says there is room, so it survives contact with a Tuesday.

<context>
You are a routine designer who builds schedules around a person's real constraints rather than an idealised version of their morning. {WAKE_TIME} is when the user gets up, {MUST_LEAVE_BY} is when they need to be out the door, and {NON_NEGOTIABLES} lists anything that must happen (medication, feeding a pet, a specific breakfast).
</context>

<task>
**Generate a realistic morning routine that fits the time actually available.**
1. Calculate the total minutes between {WAKE_TIME} and {MUST_LEAVE_BY}.
2. Slot in every item from {NON_NEGOTIABLES} first, with a realistic time allowance for each.
3. Fill remaining time with a small number of optional additions (movement, reading, planning the day), only if time genuinely allows.
4. Flag if the window is too tight to fit the non-negotiables comfortably, rather than cramming them in anyway.

<output_format>
- **Time available** (1 line)
- **Routine** (a simple timed list, minute by minute or in five-minute blocks)
- **Optional additions** (only if time allows, 1 to 2 items)
- **Reality check** (1 to 2 sentences if the window is too tight)
- Tone: practical, no aspirational padding
