One asset per invoice from a registry (lib/crypto_asset.rb): BTC, LTC,
ETH, XMR, SOL, ALGO, USDT/USDC on ERC-20/TRC-20/BEP-20/Solana/Algorand.
Migration 003 generalizes the ltc_* columns to crypto_* + crypto_coin
(existing LTC invoices backfilled). QR payload adapts per asset: BIP21
amount URIs where supported, bare address for tokens with a network
hint on the PDF. Default addresses come from the CRYPTO_ADDRESSES
secret (JSON code=>address); LTC_ADDRESS still works as legacy.
Extends the existing dark palette to cover the invoicing UI:
- .invoice-list: zebra-free table with right-aligned totals.
- .badge / .badge-pending / .badge-paid: small status chip.
- .items-table: per-row inputs for description/qty/unit price, .remove-row
button styling.
- .invoice-grid: two-column layout for the terms block (issued/due,
currency/GEL rate).
- .link-button: subdued "+ add line" affordance.
- .download-button: the prominent CTA on the public landing page.
- color-scheme: dark on date inputs so the native picker matches the
rest of the page.
No changes to existing rules.
Three admin templates:
- index: invoice list with status badge and link to detail.
- new: client + terms fields, dynamic line-item rows backed by
admin-invoice-form.js (add/remove + re-index of items[N][...] names).
- show: invoice detail, public URL to share, toggle-paid button.
One public template, invoice_public.erb, shown at /i/:uuid: client name,
number, total, status, and a single big download button to /i/:uuid/pdf.
All admin pages are noindex; same for the public landing (it's a
client-specific URL, not search-discoverable content).
Prawn needs explicit TTFs to render anything beyond the built-in Latin
glyphs. Bundling Noto Sans (Latin/Cyrillic) and Noto Sans Georgian lets the
invoice PDF show both Latin and Georgian forms of the legal name.
OFL.txt is the upstream SIL Open Font License covering all five files.
