# Space Exploration Task Type

Math problem worksheets with space theme: hero images, footer panoramas, icon-decorated problem cards.

## Base References

- Base template: `src/templates/space-base.html` (layout/styling reference)
- Example outputs in `docs/` (existing worksheets serve as reference for new ones)

## What to Vary Per Worksheet

1. **Hero image** — from `assets/hero-images/spaceship{1-9}.jpeg`
2. **Footer image** — from `assets/footers/planet{1-9}.jpeg`
3. **Hero position** — `flex-row-reverse` (hero right) or default (hero left)
4. **Problem icons** — from `assets/icons/pack1/` or `pack2/`. **Every icon must be unique across the entire document** (no repeats across pages). Shuffle minerals and plants randomly — do not sort by type
5. **Problem alignment** — randomly assign `justify-start`, `justify-center`, or `justify-end` per card. No patterns — should look chaotic/scattered
6. **Problems** — generate from the task description in the `.md` file

## Layout Structure (do not change)

- Page: `w-[210mm] h-[297mm]` white container
- Footer: absolute bottom, `h-[80mm]`, with white-to-transparent fade on top. **No `overflow-hidden`** on footer (causes 1px hairline artifact in PDF)
- Footer bubble: absolute `bottom-[12mm]`, pill-shaped with semi-transparent white bg
- Content area: `px-[12mm] pt-[4mm] pb-[65mm]` flex column
- Header: hero image `w-[48%]` + title block centered, `flex-row-reverse` for hero-right
- Footer gradient: `linear-gradient(to bottom, white 0%, rgba(255,255,255,0.6) 25%, transparent 50%)` with `h-full`
- Problems: `grid grid-cols-2 gap-x-3 gap-y-[3px]` — 20 problems total
- Each problem: 58px icon outside pill + `text-[1.2rem]` expression + `w-16` answer underline inside pill
- Font: Nunito via Google Fonts
- Uses Tailwind CDN
