# ATB-52: CSS Token Extraction Implementation Plan
2
+
3
+
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
4
+
5
+
**Goal:** Extract all remaining hardcoded CSS values in `theme.css` into the design token system and ship `neobrutal-light.json` + `neobrutal-dark.json` preset files.
6
+
7
+
**Architecture:** `theme.css` already uses `var(--token)` for ~95% of values. Two sections (moderation UI, structure UI) were added separately and never aligned. The preset is currently a TypeScript named export; we convert it to JSON (default import) which is already supported by `resolveJsonModule: true` in `tsconfig.base.json`. `tokensToCss()` and the `BaseLayout` injection are unchanged.
8
+
9
+
**Tech Stack:** CSS custom properties, TypeScript JSON imports, Vitest

## Running tests
16
+
17
+
From the repo root (requires devenv PATH):
18
+
19
+
```bash
20
+
PATH=/path/to/repo/.devenv/profile/bin:/bin:/usr/bin:$PATH pnpm --filter @atbb/web test
21
+
```
22
+
23
+
Or from inside `apps/web/`:
24
+
25
+
```bash
26
+
PATH=/path/to/repo/.devenv/profile/bin:/bin:/usr/bin:$PATH pnpm exec vitest run
27
+
```
28
+
29
+
If you're in a worktree, the `.devenv` symlink is absent — use the absolute path to the main repo's `.devenv/profile/bin`.

## Task 1: Write failing preset completeness tests
34
+
35
+
**Files:**
36
+
- Create: `apps/web/src/styles/presets/__tests__/presets.test.ts`
37
+
38
+
**Step 1: Create the test file**
39
+
40
+
```typescript
41
+
// apps/web/src/styles/presets/__tests__/presets.test.ts
42
+
import { describe, it, expect } from "vitest";
43
+
import neobrutalLight from "../neobrutal-light.json";
44
+
import neobrutalDark from "../neobrutal-dark.json";
45

import { tokensToCss } from "../../../lib/theme.js";
46

90

it("has a darker background than the light preset", () => {
91

expect((neobrutalDark as Record<string, string>)["color-bg"]).not.toBe(
92

(neobrutalLight as Record<string, string>)["color-bg"]
93
+

});
95

96

100
+
});
101
+
});
102
+
```
103
+
104
+
**Step 2: Run the test to verify it fails**
105
+
106
+
Expected: compile error — `neobrutal-light.json` and `neobrutal-dark.json` don't exist yet.
107
+
108
+
```bash
109

## Task 4: Update `base.tsx` to import from JSON
243
+
244
+
**Files:**
245
+
- Modify: `apps/web/src/layouts/base.tsx:1-6`
246
+
247
+
**Step 1: Replace the import and usage**
248
+
249
+
Old lines 1–6:
250
+
```typescript
251
+
import type { FC, PropsWithChildren } from "hono/jsx";
252
+
import { tokensToCss } from "../lib/theme.js";
253
+
import { neobrutalLight } from "../styles/presets/neobrutal-light.js";
254
+
import type { WebSession } from "../lib/session.js";
255
+
256
+
const ROOT_CSS = `:root { ${tokensToCss(neobrutalLight)} }`;
257
+
```
258
+
259
+
New lines 1–6:
260
+
```typescript
261
+
import type { FC, PropsWithChildren } from "hono/jsx";
262
+
import { tokensToCss } from "../lib/theme.js";
263
+
import neobrutalLight from "../styles/presets/neobrutal-light.json";
264
+
import type { WebSession } from "../lib/session.js";
265
+
266
+
const ROOT_CSS = `:root { ${tokensToCss(neobrutalLight as Record<string, string>)} }`;
267
+
```
268
+
269
+
Note: TypeScript infers JSON imports as their literal type (e.g., `{ "color-bg": string; ... }`), which is not directly assignable to `Record<string, string>` without a cast. The `as Record<string, string>` cast is safe here — all values in the JSON are strings.
270
+
271
+
**Step 2: Run the base layout tests**
272
+
273
+
```bash
274
+
pnpm exec vitest run src/layouts/__tests__/base.test.tsx
275
+
```
276
+
277
+
Expected: all tests PASS (especially "injects neobrutal tokens as :root CSS custom properties" which checks `--color-bg:` and `--color-primary:` appear in the HTML).
278
+
279
+
---
280
+
281
+
## Task 5: Delete `neobrutal-light.ts`
282
+
283
+
**Files:**
284
+
- Delete: `apps/web/src/styles/presets/neobrutal-light.ts`
285
+
286
+
**Step 1: Delete the file**
287
+
288
+
```bash
289
+
rm apps/web/src/styles/presets/neobrutal-light.ts
290
+
```
291
+
292
+
**Step 2: Run the full test suite to verify nothing else imported it**
293
+
294
+
```bash
295
+
pnpm exec vitest run
296
+
```
297
+
298
+
Expected: all tests PASS. If any test fails with "cannot find module neobrutal-light.js", search for other imports of this file and update them.
299
+
300
+
**Step 3: Commit**
301
+
302
+
```bash
303
+
git add apps/web/src/styles/presets/
304
+
git add apps/web/src/layouts/base.tsx
305
+
git commit -m "feat(web): convert presets to JSON, add neobrutal-dark, add font-size-xs token (ATB-52)"
306
+
```
307
+

+
## Task 6: Fix moderation UI hardcoded values in `theme.css`
311
+
312
+
**Files:**
313
+
- Modify: `apps/web/public/static/css/theme.css` (lines ~751–821)
314
+
315
+
The existing base layout tests act as the regression harness for CSS — they verify the layout renders and tokens are injected. The visual regression (forum looks identical) requires a manual browser check after this task.
316
+
317
+
**Step 1: Replace the entire moderation UI section**
318
+
319
+
Find this block (from `/* ─── Moderation UI ──` to just before `/* ═══ RESPONSIVE BREAKPOINTS`):
320

```css
322
+
/* ─── Moderation UI ──────────────────────────────────────────────────────── */

390
+
font-size: 1.25rem;
391
+
}
392
+
```
393
+
394
+
Replace with:
395
+
396
+
```css
397

## Task 7: Fix structure UI hardcoded fallback values in `theme.css`
480
+
481
+
**Files:**
482
+
- Modify: `apps/web/public/static/css/theme.css` (lines ~1003–1154)
483
+
484
+
These are fallback values in `var(--token, fallback)` form — the fallback is a hardcoded value. Remove the fallbacks.
485
+
486
+
**Step 1: Apply the following replacements** (use your editor's find-and-replace):
487
+
488
+
| Find | Replace |
489
+
|------|---------|
490
+
| `var(--space-6, 1.5rem)` | `var(--space-lg)` |
491
+
| `var(--radius, 0.5rem)` | `var(--radius)` |
492
+
| `var(--radius, 0.375rem)` | `var(--radius)` |
493
+
| `var(--font-size-xl, 2rem)` | `var(--font-size-xl)` |
494
+
495
+
There are multiple occurrences of `var(--radius, ...)` in the structure UI — replace all of them.
496
+
497
+
**Step 2: Run tests**
498
+
499
+
```bash
500
+
pnpm exec vitest run
501
+
```
502
+
503
+
Expected: all tests PASS.
504
+
505
+
**Step 3: Commit**
506
+
507
+
```bash
508
+
git add apps/web/public/static/css/theme.css
509
+
git commit -m "fix(web): replace hardcoded CSS values with design tokens in mod and structure UI (ATB-52)"
510
+
```
511
+
512
+
---
513
+
514
+
## Task 8: Verify no hardcoded values remain
515
+
516
+
**Step 1: Search for remaining hardcoded values**
517
+
518
+
Check for any remaining hardcoded color hex values:
519
+
```bash
520
+
grep -n '#[0-9a-fA-F]\{3,6\}' apps/web/public/static/css/theme.css
521
+
```
522
+
523
+
Expected: no matches (the `rgba(0, 0, 0, 0.5)` backdrop uses `rgba` not hex — this is acceptable since it's a structural opacity value that isn't part of the token schema).
524
+
525
+
Check for remaining hardcoded pixel sizes outside responsive breakpoints:
526
+
```bash
527
+
grep -n '[0-9]\+px' apps/web/public/static/css/theme.css
528
+
```
529
+
530
+
Review the output — pixel values inside `@media (min-width: ...)` breakpoint declarations are expected. Any pixel values in rule bodies are a problem.
531
+
532
+
Check for non-standard spacing token names:
533
+
```bash
534
+
grep -n 'var(--space-[0-9]' apps/web/public/static/css/theme.css
535
+
```
536
+
537
+
Expected: no matches.
538
+
539
+
**Step 2: Manual visual check**
540
+
541
+
Start the dev server:
542
+
```bash
543
+
pnpm --filter @atbb/web dev
544
+
```
545
+
546
+
Visit each view and confirm visual appearance is unchanged:
547
+
- Homepage (category/board list)
548
+
- Board page (topic list)
549
+
- Topic page (post thread)
550
+
- New topic compose form
551
+
- Login form
552
+
- Admin panel index
553
+
- Admin members page
554
+
- Admin structure management page
555
+
- Any mod action dialogs
556
+
557
+

558
+
559
+
## Task 9: Run full test suite and final commit
560
+
561
+
**Step 1: Run all tests**
562
+
563
+
```bash
564
+
pnpm --filter @atbb/web test
565
+
```
566
+
567
+
Expected: all tests PASS.
568
+
569
+
**Step 2: Update Linear**
570
+
571
+
Mark ATB-52 as Done and add a comment summarizing:
572
+
- `theme.css` now zero hardcoded values
573
+
- `neobrutal-light.json` and `neobrutal-dark.json` ship as preset files
574
+
- `--font-size-xs: 12px` added to the token schema
575
+
- `tokensToCss()` unchanged, fully tested
576
+
577
+
**Step 3: Update the plan doc status**
578
+
579
+
In `docs/plans/2026-03-02-atb-52-css-token-extraction.md`, update the header status or move to `docs/plans/complete/` when the PR is merged.
