A klammer that reaches itself, directly or through a cycle, expanded
until the C++ stack was exhausted: the process died from SIGSEGV with no
message and no location. The former limit guarded only the top-level
fixed-point iteration, never the descent through klammer application. A
depth guard now raises a recursion error naming the klammer and where it
was applied. The same loop's termination test moves from "the katom list
stopped growing" to "a pass applied no klammer", since a klammer whose
body expands to nothing is a reduction that adds no katoms; exceeding the
round limit is now an error rather than a message followed by rendering a
document with live klammers still in it.
ktext --check locates every klammer application written in a document or
in a klammer body and checks name existence, argument count, option
names, and target coverage without applying anything, reporting all
problems at once. This is possible because Klammertext has no catcodes:
katom structure is fixed when a file is read, so a klammer body has a
determinate shape before it is expanded. The check therefore reaches what
the engine cannot -- the branch of a @cond that is not selected, and
bodies a given render never enters.
@cond's set of truth values is an open language question, so its meaning
is unchanged here; an unrecognized predicate now warns, giving its value
and location.
tst/ gains recursion_test.sh (7 cases) and check_test.sh (19 cases), and
this snapshot's test Makefile is generated from the shipped suite list so
the two cannot drift apart.

The @@@klammerset system command formally declares a klammerset — a
named, logically related group of klammer definitions — with an
operative, idempotent declaration (:requires and :files load in order
at the declaration point, relative to the declaring file). A bare
symbol given to ktext -k, kdesc --input, or :requires resolves to
x/x.k on the search path: the document's directory, then
KLAMMERTEXT_KLAMMERSETS, then KLAMMERTEXT_HOME; kdesc --klammerset
lists the available sets. sks/sks.k is the first declared klammerset,
so `-k sks` loads the SKS by name. The engine's lookup classes were
renamed *_set → *_registry to keep the two concepts apart, and the
whole C++ tree now follows standard const-correctness conventions.
tst/ gains klammerset_test.sh (18 cases).

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).
Curated source subset assembled by klammertext-dev's doc/make_dist.sh: the Klammermachine (mac), the Standard Klammer Set (sks), the commands (com), editor plugins and install guides (doc), a test subset (tst), and lib/bin placeholders. Builds with 'make -C com'.
