v0.2 — Description Sync & Template Stabilization

Date: April 6, 2026

Automated GTM UI descriptions — A new sync engine (sync-descriptions.ts) generates GTM UI help text directly from AST test examples, ensuring the GTM interface always shows accurate, up-to-date input/output demonstrations.
Template corruption fix — Repaired JSON schema corruption across 25+ templates caused by a regex token interpolation bug ($ in replacement strings). All templates now pass strict JSON validation.
Cleaner website descriptions — Variable pages on the documentation site now show only the base description, stripping out the example blocks that are only needed in the GTM UI.

Area	What Changed
`sync-descriptions.ts`	New script: parses `@display` annotations from `[example]` tests and injects formatted examples into the GTM `help` field
`tpl-parser.ts`	`parseHelpField()` now splits on `***` separator to strip examples from website descriptions
`astro.config.mjs`	Added `site` field for sitemap generation
25+ `.tpl` files	Repaired corrupted JSON in `help` parameters (condition, object, string, url categories)

Date: April 5, 2026

First tagged baseline of the template library. All 250+ variable templates with working tests, documentation site, and GTM container exports.
