ATTR.4 Report binder: Unicode text, Arabic and Hebrew right to left

Owner 2026-11-03. Typed pages now embed a subset font only when the text needs one: Latin extended, Greek and Cyrillic (Liberation Sans), Arabic, Hebrew, Armenian and Georgian (DejaVu Sans, newly vendored in assets/vendor/rtl-sans), Thai, and Chinese, Japanese and Korean (10 MB, fetched on first need). Arabic letters join and right-to-left lines are ordered with numbers and Latin kept in order (lib/report/bidi.js, a simplified bidi, no bidi control characters). Limits: Devanagari and other Indic scripts have no font or shaper, so they still print as ? and are counted; those stretches print regular, never bold or italic; text copied from Arabic pages comes out as presentation forms in visual order; the page stamp leaves off a project name it cannot print. A font that fails to load prints ? and the dialog says so. Checked by eye on one rendered page, not by a native reader. In /lab, not released.
