Date format
- Replace hardcoded toLocaleDateString with a config-driven formatter
- date-format key in config (default "d MMMM YYYY") supports tokens:
d, dd, M, MM, MMM, MMMM, YY, YYYY (regex replace, longest match first)
Paper format
- paper-format key in config: "a4" (default) or "letter"
- Passed directly to jsPDF; page dimensions adjusted accordingly
Tax system redesign
- Remove single-select tax-rates from config; add tax-types list, each
with a key and per-language labels (VAT, GST, Sales Tax, Withholding,
Other)
- Totals section now has a dynamic tax-tbody: each row has a number
field, a % / Amount selector, and a tax-type label selector; rows
are added with "+ Add new tax" and removed with ×
- calcTotals iterates tLines: % rows compute sub × (val/100), Amount
rows use the fixed value directly; each row shows its calculated
amount live
- gatherData collects all tax lines into a taxes[] array with lineLabel
(e.g. "VAT 7%" or "GST (50.00)") and amt; both preview and PDF
render one row per tax entry
- relabel() rebuilds tax-line dropdowns on language switch

- Date picker: change invoice date from month picker to full date picker
(type=date, formatted as "19 May 2026" in output)
- Invoice currency: add currency selector under invoice date, populated
from config.currencies list, saved to localStorage; shown in invoice
meta block on both preview and PDF
- Recipient currency: add currency field to each charge-to entry in
config.yml; selecting a predefined recipient auto-sets invoice currency
- Lock predefined recipients: selecting a predefined charge-to entry
locks all its fields (pointer-events off + muted style via #ct-fields
.locked); switching to Other or clearing unlocks them
- Fix foreign-currency exchange rate calculation: the formula was
inverted (per / rate instead of per * rate). If 1 USD = 32 local and
per-item is USD 100, local price is now correctly 100 × 32 = 3200,
not 100 / 32 = 3.125. Fix applied in calcFxFromPer, calcLine display,
and gatherData (foreignTot = per × qty, the foreign-currency total).
Updated fx note text to the specified format:
"Converted from USD: 1 USD = 32.00000 THB. Per item: USD 100.00,
line total: USD 500.00"

The browser print-to-PDF approach requires the user to manually toggle
"Background graphics" on and "Headers and footers" off — impossible to
control programmatically. Replace with direct jsPDF generation:
- Loads jsPDF 2.5.1 UMD from CDN
- buildPDF() draws the invoice programmatically using Helvetica (PDF
built-in font, no embedding needed)
- Layout: sender/title header, navy rule, charge-to block with navy
accent bar, line-items table (navy header, alternating rows, multi-
line description wrapping, foreign-currency sub-row), totals with
navy To-Pay bar — all in mm on A4
- PDF downloads directly as invoice-{no}.pdf with no dialog
- HTML preview overlay retained for review before download
- Replace "print-invoice" config key with "download-pdf"

Static single-page invoice app per spec. Features:
- Multilingual UI (EN/DE/FR/NO) loaded from config.yml; form always
prints in the default language
- Sender fields + invoice details (date, project code, invoice no.)
persisted in localStorage; invoice number auto-increments after
each generation
- Predefined charge-to recipients selectable from config, or manual entry
- Dynamic invoice line items: predefined products with UOM/price
pre-fill, free-text fallback, foreign-currency sub-row with
exchange-rate and per-item price that calculates back to local currency
- Subtotal / tax (configurable rates) / paid / to-pay calculated live
- "Generate Invoice" renders a clean A4-formatted preview overlay;
"Print / Save as PDF" triggers browser print-to-PDF
