- bump @toon-format/spec to ^3.3.0; update SPEC.md pointer and badges
- docs: align number-form prose with §2 carve-out (canonical in [1e-6, 1e21) or zero; exponent form permitted outside)
- docs/reference/spec.md: add lowercase booleans/null to encoder checklist; add Java to Appendix F language list
- docs/reference/efficiency-formalization.md: drop overstated "matching TOON's requirement" claim
- packages/toon/README.md: drop "What's New in v3.2" section (now stale)
All 593 tests pass (packages/toon: 497, packages/cli: 96). Encoder remains conformant by default under the v3.3 §2 carve-out via String(value).
- Canonical empty-array form (`key: []` / root `[]`) replaces `key[0]:`
in format-overview, syntax-cheatsheet, and the efficiency-formalization
worked example. Legacy form still decodes.
- Escape tables grow a `\uXXXX` row covering U+0000-U+001F outside
\n/\r/\t, with a note rejecting lone-surrogate \uXXXX values.
- "Special characters" lists widened to "any control character (U+0000-U+001F)"
instead of the LF/HTAB/CR triplet.
- Tabular eligibility note adds the "at least one key" rule so arrays
containing an empty {} fall back to the expanded list.
- New short example for nested arrays-of-objects as list items (`- [N]:`).
- API reference: Date row gets an info callout noting it's an
implementation choice the spec leaves open; strict-mode bullet list
picks up header structure, duplicate sibling keys, path-expansion
conflicts, and lone-surrogate escapes; Expansion Conflict Resolution
notes the matching duplicate-key policy.
- §17 IANA anchor fix in getting-started media-type paragraph.
