036022cc17 spec: rational numbers — 1/3 literals, arithmetic, numeric tower integration 
SxRational type in OCaml (Rational of int * int, stored reduced, denom>0)
and JS (SxRational class with _rational marker). n/d reader syntax in
spec/parser.sx. Arithmetic contagion: int op rational → rational, rational
op float → float. JS keeps int/int → float for CSS backward compatibility.
OCaml as_number + safe_eq extended for cross-type rational equality so
(= 2.5 5/2) → true. 62 tests in test-rationals.sx, all pass.
JS: 2232 passed. OCaml: 4532 passed (+11 vs pre-fix baseline).

4b600f17e8 spec: character type (char? char->integer #\a literals + predicates) 
- Add SxChar tagged object {_char, codepoint} to JS platform
- char? char->integer integer->char char-upcase char-downcase
- char=? char<? char>? char<=? char>=? comparators
- char-ci=? char-ci<? char-ci>? char-ci<=? char-ci>=? case-insensitive
- char-alphabetic? char-numeric? char-whitespace? char-upper-case? char-lower-case?
- string->list (returns chars) and list->string (accepts chars)
- #\a #\space #\newline reader syntax in spec/parser.sx
- integer->char alias in spec/evaluator.sx
- js-char-renames dict in transpiler.sx for ->-containing names
- 43 tests in spec/tests/test-chars.sx, all passing

45c2f2bfb0 Add one-line comments to all defines in 5 spec files 
parser.sx (3), render.sx (15), harness.sx (21), signals.sx (23),
canonical.sx (12) — 74 comments total. Each define now has a ;;
comment explaining its purpose.

Combined with the evaluator.sx commit, all 215 defines across 6 spec
files are now documented. primitives.sx and special-forms.sx already
had :doc fields.

1a3d7b3d77 Separate core spec from web framework
All checks were successful
Build and Deploy / build-and-deploy (push) Successful in 4m49s
Details 
Three-layer architecture:
  spec/  — Core language (19 files): evaluator, parser, primitives,
           CEK machine, types, continuations. Host-independent.
  web/   — Web framework (20 files): signals, adapters, engine,
           orchestration, boot, router, CSSX. Built on core spec.
  sx/    — Application (sx-docs website). Built on web framework.

Split boundary.sx into boundary-core.sx (type-of, make-env, identical?)
and boundary-web.sx (IO primitives, signals, spreads, page helpers).

Bootstrappers search spec/ → web/ → shared/sx/ref/ for .sx files.
Original files remain in shared/sx/ref/ as fallback during transition.
All 63 tests pass.
