Tailwind #54 — Shared helpers (notifications, modals, enum)

Field	Value
GitLab	sourcecontrollers/safecall#54
Parent	#52
Roadmap	tailwind-roadmap.md
Depends on	#53 (closed)
Workflow	open

Goal

Point shared web/lib UI helpers at the Tailwind component catalog: notifications, modal open/close, visibility (hidden), and replace BulmaNotification with a framework-neutral enum whose values are catalog class names. Feature-page Bulma markup stays until later steps.

Design principles

1. Helpers emit catalog classes (notification-success, btn, modal-backdrop) — not Bulma is-* strings as the long-term API.
2. During coexistence, accept legacy Bulma class inputs only if needed for a soft transition; prefer mapping inside the helper so call sites can migrate gradually.
3. Soft/solid: never invent is-light; use *-soft catalog variants.
4. Keep data-theme rules from #53.

Acceptance criteria

• [x] BulmaNotification renamed (e.g. UiNotification) in lib/src/types/enums.ts; consumers updated; values map to catalog classes
• [x] Notification show/hide helpers use catalog notification classes
• [x] Modal helpers use catalog modal/backdrop classes (Bulma aliases OK until #62 if documented)
• [x] Visibility helper prefers .hidden; .is-hidden alias allowed until #62
• [x] Shared class builders used across many pages updated (buttons/tags/notifications)
• [x] Lib + web typecheck; server typecheck if lib enum export changes affect it

Implementation notes

• Primary touch: lib/src/types/enums.ts, web/src/lib/util.ts, notification/modal call sites (~40+ files may import the enum).
• Prefer one mapping table in the helper so pages can pass semantic names.
• Do not rewrite full page templates here — only shared strings/helpers.

Out of scope

Work	Issue
Navbar / login / settings templates	#55
User / admin page bulk markup	#56–#61
Remove Bulma	#62

Key paths

• lib/src/types/enums.ts
• web/src/lib/util.ts
• web/src/lib/version-check.ts (if it builds HTML classes)
• Grep: BulmaNotification, is-hidden, notification, modal-background

Verification

1. cd lib && bun run typecheck; cd web && bun run typecheck; cd server && bun run typecheck if lib used by server.
2. Smoke: toast success/error; open/close a modal; element hide/show.
3. Grep: no remaining BulmaNotification symbol (unless deprecated re-export removed).

Done when / handoff

1. Operator verifies → commit with Closes #54 → push gitlab.
2. Next: #55 shell + auth + settings.
