This branch moved twice at once: upstream merged KartaView (#1121, a
third keyless street-level provider sharing a new lineCoverage.js), and
the remote i18n-spanish gained the whole-interface translation work
(1993 catalog entries, translateKnown, data-i18n-runtime, the unmarked-
string detector in npm run i18n) built on the Street View merge.
Integration keeps the remote's mechanisms and re-adds KartaView on top:
- presentMeta: remote's translateHint for coverage hints, plus the
KartaView count line as its own literal tn pair (Russian plurals need
the noun inside the template; keyed off coverageLabel.noun with the
sequences pair as the default).
- uiState: upstream's highlightsSequence legend gate (KartaView's lines
do not highlight) with t('Selected').
- layer-panels.html: remote's data-i18n/data-i18n-runtime hooks plus the
sl-since-note wiring KartaView's upload-date SINCE note needs.
- kartaview viewer: the photo-navigation aria-label and img alt go
through t(), as the remote's unmarked-string detector requires.
- catalogs: remote's 1987-entry base (its refined keys supersede this
branch's earlier Street View wording) plus the KartaView entries:
coverage hints, the upload-date note, the streets count line (with
Russian one/few/many/other forms) and the viewer strings.
npm run i18n: complete, no unmarked strings. npm test: 6520/6522 (the
one failure is the pre-existing environmental OPENAI_API_KEY leak in
devFreshDotenv). Build passes.
