# PDF Generation Pagination

Source: `src/lib/pdf.ts`

## Page-break logic

Each service calculates its height before rendering. Page break triggers when `y + serviceHeight > CONTENT_BOTTOM - FOOTER_HEIGHT`.

Key constants:
- `CONTENT_BOTTOM = PAGE_H - MARGIN` (772)
- `FOOTER_HEIGHT = 35` (reserved for separator + footer text + page number)

## Height calculation (must match rendering yPos increments)

```
svcH = 0
if hasDecision:     svcH += 5   // badge
svcH += 6                       // name + price
if priority:        svcH += 16  // priority label + reason
if recommendation:  svcH += 8
if explanation:     svcH += lines * 5 + 2
if partsNotInStock: svcH += 8 + (deliveryTime ? 8 : 0)
if aftermarket:     svcH += 8 + (partsList ? 8 : 0)
svcH += 6                       // separator + spacing
```

## After page break

- Call `doc.addPage()` then set `yPos = MARGIN`
- **Redraw current section header** (SERVICES APPROVED / POSTPONED SERVICES) so new page has context
- Summary box uses same FOOTER_HEIGHT check before rendering

## Footer

Drawn on EVERY page via post-render loop:
```ts
const totalPages = doc.getNumberOfPages();
for (let i = 1; i <= totalPages; i++) {
    drawFooter(doc, i, totalPages, settings, shopChargeAmount);
}
```
Footer includes: separator line, shop message, validity note, "Page N of M"

## String rendering (jspdf 4.x)

NEVER pass arrays to `doc.text()` — jspdf 4.x uses different internal line spacing than manual yPos tracking, causing cascading desync and text overlap. Always render `splitTextToSize()` results per-line:
```ts
doc.splitTextToSize(text, CW).forEach((line) => {
    doc.text(line, MARGIN, y);
    y += 5;
});
```
