v0.39.0 — Every law reference in the app explains itself

An invoicing app that talks about Polish VAT has to name the law — but a code like art. 89b ust. 1 next to a figure explains nothing to the person the app is built for. There were about forty such references, written out as plain text and copied across three languages, which meant the same norm could be spelled two different ways on two different screens.

• Every reference is now a link. Click it and a small panel opens: what the section actually says, in your language, with the operative words highlighted — and a link to the official text on eli.gov.pl if you want the wording itself. It works inside a field label too, so the law sits next to the input it governs.
• 29 sections, explained in plain language. VAT deduction proportion, the annual correction, bad-debt relief on both sides, the exemption limit and what it never covers, correction tax points, split payment, simplified invoices, farmer purchases, the lump-sum deductions, and the catalogue marks for JPK — including one norm that is not from the VAT act at all, but from pharmaceutical law.
• The reference itself is written once. The signature (art. 108a ust. 1a ustawy o VAT) now lives in a single record and is printed from there on every screen and in every language. Only the explanation is translated — a Polish norm is cited in Polish everywhere, which is exactly how your accountant will read it back to you.
• Where a panel cannot open, the reference is still readable. A toast, an item in a dropdown, a one-line alert, a PDF, an answer from the AI assistant — each prints the full signature instead of leaving you with markup or a bare code.
• The split-payment hint now states the whole rule. It used to appear on any invoice over 15 000 zł and call split payment mandatory. It is mandatory only when the invoice also covers goods or services from Annex 15, and only above 15 000 — not at exactly 15 000. The hint now appears in that case and says both conditions outright.
• Bad-debt relief now names its deadline. The explanation of the seller's side says what the screen never did: the relief can be claimed no later than three years from the end of the year the invoice was issued.
• It cannot quietly come undone. A new law reference written as plain text on a live screen now fails the build, and every explanation is checked to exist in all three languages before release.
