Sync with klammertext-dev through b90b0e09: - Argument types end to end: :python_cast values are applied (Python @eval receives real bools/numbers/lists), argument values are validated against their argtype patterns with the argtype's description as the error message, argtypes can declare :default (overridable per declaration), and parameterized type families are supported: rest(N) casts a rest argument to an N-dimensional list (bar-count = dimension). - Unified indexed_range syntax (selector with parenthesized subsets, composable mnemonic names) for table lines and spans. - Table klammer: caption fonts fixed in both targets, :column_width / :leading / :colsep wired, :colspan and :rowspan render (HTML attributes; \multicolumn / \multirow), calculated cell values (:calc) with prefix operators, display-precision semantics, :calc_format and :decimal period|comma. - Fonts: closed-world resolution on the Klammertext font store (infrastructure in mac/font_store; no Google Fonts links or fetch). Default fonts live in the top-level fnt/; additional fonts install into KLAMMERTEXT_FONTS directories via kdesc --font (list, samples, preview, install — classification by font metadata). CSS font family names are quoted (digit-initial families were silently lost). - Environment files moved from mac/env/ to the top-level env/; shell profiles source env/runtime.env. Dead per-host variants removed. - Container: fnt/ ships in the image; curl removed (no network use).
