# WP-10 — CIBG button fidelity

Status: todo
Phase: 2 — CIBG fidelity

## Why

The vendored CIBG build ships `.btn-primary / .btn-secondary / .btn-danger / .btn-ghost /
.btn-link / .btn-link--underline / .btn-inline` — and **no** `.btn-outline-primary`,
`.btn-outline-secondary`, or `.btn-sm` (verified absent from
`public/cibg-huisstijl/css/huisstijl.min.css`). Three components emit those dead classes
and render as unstyled Bootstrap defaults instead of CIBG buttons.

## Read first

- https://designsystem.cibg.nl/componenten/knoppen/ (or grep the vendored CSS)
- `src/app/shared/ui/button/button.component.ts` (~line 14)
- `src/app/shared/ui/upload/file-input/file-input.component.ts` (~line 38)
- `src/app/shared/ui/rich-text-editor/rich-text-editor.component.ts` (toolbar, ~lines 55-60)

## Decisions (pre-made, don't relitigate)

- `variant='secondary'` → `.btn-secondary` (CIBG's documented secondary).
- RTE toolbar buttons → `.btn-ghost`; drop `.btn-sm` — if the toolbar needs a smaller
  size, that's token-bridge CSS carrying the CIBG-gap marker (format per WP-13; define it
  inline if WP-13 hasn't run).
- Add `'ghost'` to the atom's variant union (CIBG documents it; the RTE needs it).
- Icon affordances (chevron/pijl): implement **only if** icon classes exist in the
  vendored CSS — inspect first; otherwise record as a gap in the WP-13 register and skip.

## Files

- `src/app/shared/ui/button/button.component.ts` + `button.stories.ts`
- `src/app/shared/ui/upload/file-input/file-input.component.ts`
- `src/app/shared/ui/rich-text-editor/rich-text-editor.component.ts`
- Any story/snapshot referencing the old classes

## Steps

1. Fix the variant map in the button atom; add `ghost`.
2. file-input label-button → `btn btn-secondary`.
3. RTE toolbar → `btn btn-ghost` (+ marked size CSS if needed).
4. Grep-check `btn-outline`/`btn-sm` gone repo-wide.
5. Storybook visual review of Button (all variants), FileInput, RichTextEditor against
   designsystem.cibg.nl/componenten/knoppen.

## Acceptance criteria

- [ ] `grep -rn "btn-outline\|btn-sm" src/app` → empty.
- [ ] Button story shows all CIBG variants incl. ghost; visuals match the design system.
- [ ] Axe still green (contrast can change with real button styles).

## Verification

GREEN + `npm run test-storybook:ci`. Manual Storybook review of the three components.

## Out of scope

Other invented classes (WP-11); datablock (WP-12).

## Risks

Visual regressions where outline-secondary "worked by accident" via Bootstrap base rules
— the story review step is the catch.
