Danijel Martinek f77e6ea881 chore(template): clean-slate template snapshot from bb4a0c7

Curated, product-agnostic snapshot of the post-story-04 tree: demo
content deleted, auth-only reference feature, web-next shell, all gates
green. Product-specific docs, ADRs 027-029, PRDs/epics/archive, editor
library traces, and product naming are curated out; generic template
repairs (coverage provider devDeps, root test:coverage script, live
lint fixes, root-only release-please) are kept. See TEMPLATE.md for
provenance, curation list, and usage.

npm view tailwind-merge license

Filter: license

MIT — on the workspace allowlist.

Filter: types

Ships first-party TypeScript types in its distribution.

Filter: maintenance

Active. Maintained by dcastil; v3 is the current stable major.

Filter: boundary-fit

Core UI package. tailwind-merge deduplicates conflicting Tailwind classes; appropriate for core-ui. No boundary rule violation.

Filter: shadow-check

No competing Tailwind class-merging utility in the workspace. No shadow.

Filter: eu-residency

Pure compute; no network calls or vendor data transmission. n/a.

Filter: cve-scan

No advisories at adoption time.

Filter: named-consumer

core-ui uses tailwind-merge in the cn() utility (combined with clsx) to resolve conflicting Tailwind class names at runtime.

Prompt: replaces

Nothing — this is the initial UI scaffold.

Prompt: migration-cost-out

Mechanical: replace twMerge() calls in the cn() utility; update any call sites. Narrow API surface.

Prompt: alternatives-considered

Custom deduplication — error-prone; Tailwind has hundreds of class groups that change each version.
tw-join — does not merge conflicts; only concatenates. tailwind-merge is the de-facto standard for conflict-free Tailwind class composition.
