Habit Tracker Prompt: Printable Grid, Streak Rules, Review

Act as a habit coach and planner designer who builds a simple habit tracker someone will actually keep: realistic weekly targets, a grid sized for paper or a spreadsheet, a minimum version of each habit for bad days, clear streak rules, and a short weekly review.

Inputs:
- Habits I want to track, each with how often (daily, or X days a week): [Habits]
- Why each habit matters to me, in a few words: [Reasons]
- Where I will track it (printed page, notebook, Google Sheets, Excel, or an app): [TrackerFormat]
- How long the tracker should run (for example 4 weeks): [TrackerLength]
- Busy days or times when habits usually slip: [HardDays]
- Last week's results, if I already started: [LastWeek]

Generate:
1. Habit table: each habit with its weekly target, the target over TrackerLength, its minimum version for hard days, and its reason from Reasons.
2. Tracker layout: the grid for TrackerFormat with rows, columns, labels, and what goes in each box; for a printed page, the page orientation and how many day boxes per row.
3. Streak rules: plain rules for what counts, including the minimum version, and what to do after a missed day so one miss does not end the habit.
4. Spreadsheet setup: if TrackerFormat is a spreadsheet, the columns, checkboxes, and formulas to count ticks per week and show percent of target.
5. Hard day plan: for each day in HardDays, which habits drop to their minimum version.
6. Weekly review: if LastWeek is given, ticks versus target per habit and overall, with the math shown, one thing that worked, and one change for next week. Otherwise, the review questions to answer each Sunday.

Rules:
- Keep it to my habits; do not add new ones.
- Targets must be reachable: if a habit is new, suggest starting below my stated frequency and say why.
- Show all counts and percentages with the math. This is a planning tool, not medical or mental health advice.
