Context - BugHerd #231 (epic LS-2934) flags 9 WCAG AA color-contrast violations across 4 DEV URLs - Two independent root causes: image captions on dark-background posts, active blog filter pill - Full Spec Kit workflow run: specify, clarify, plan, tasks, checklist, analyze Spec & Planning - spec.md: two prioritized user stories (P1 captions, P2 filter pill), 8 functional requirements, 4 success criteria - Clarified verification scope: fix inherits sitewide by design, but only the 4 flagged URLs are tested - plan.md, research.md, data-model.md: confirms both fixes reuse existing color tokens (text--on-dark-muted, text--on-light) — no new tokens needed - quickstart.md: end-to-end verification steps using SINGLE_PAGE_URL against DEV, no new BugHerd tasks created Tasks & Quality Gates - tasks.md: 20 tasks across setup, two independent user-story phases, and polish - checklists/requirements.md, checklists/accessibility.md: spec-quality and requirements-quality reviews Analysis Fixes - Closed a Constitution Principle VI gap: added phpcs/php -l validation for changed PHP files - Corrected a false assumption that captions needed dark/light selector scoping — this theme uses one active global style sitewide, not per-post; caption fix is now unconditional, matching existing taxonomy-filter.scss pattern - Documented FR-004 (new token parity) as intentionally not triggered, and added layout/spacing regression checks Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
…(LS-2934) Root Cause 1 — Image captions - Added new SCSS partial for .wp-element-caption/figcaption color - Uses existing --text--on-dark-muted token (10.1:1 against site background) - Applied unconditionally, matching taxonomy-filter.scss's existing pattern - Registered new file in package.json build scripts, inc/animations.php, and functions.php Root Cause 2 — Blog taxonomy filter pill - Swapped .taxonomy-filter-current color from --text--on-dark to --text--on-light (6.57:1) - Also fixed the same color in its :hover/:focus-visible state to prevent reverting to the failing color Verification - Confirmed zero serious/critical color-contrast violations on localhost /blog/ via scoped Playwright run - DEV re-verification for the 3 caption URLs deferred until after merge/deploy, per plan - Manually confirmed no regression to default/hover pill states or layout Context - BugHerd #231, epic LS-2934, closes out remaining open work on the epic - Full Spec Kit workflow: spec, clarify, plan, tasks, checklist, analyze, implement - Analysis caught and fixed a Constitution Principle VI gap (missing phpcs/php -l gate) and a false assumption about per-post dark/light scoping (site uses one active global style sitewide, not per-post)

Inline comments:
In `@inc/animations.php`:
- Around line 217-220: Update the caption color rule in
assets/css/image-captions.css so the dark-surface token applies only within the
repository’s dark-background post context, rather than globally to every
.wp-element-caption and figcaption. Preserve caption styling in light-background
contexts and keep the existing image-captions registration in the image-captions
handle unchanged.
In `@specs/002-color-contrast-fixes/data-model.md`:
- Line 31: Update the States description to mark the active
`.taxonomy-filter-current` hover and focus-visible states as changed to
`--text--on-light`, rather than describing `:hover` as unaffected; keep the
default state and unrelated hover behavior unchanged.
In `@specs/002-color-contrast-fixes/quickstart.md`:
- Line 30: Update the verification instructions near “All three must pass” to
document that npm run theme:validate may fail due to the pre-existing missing
styles/light.json baseline, while requiring the other two checks to pass and
confirming the validation failure matches that known condition.
In `@specs/002-color-contrast-fixes/tasks.md`:
- Line 75: Update task T016 to remain unchecked because its required DEV
verification has not been completed; preserve the local Playwright result as
informational or move it to a separate completed local-validation task without
marking T016 complete.
In `@src/scss/structural/image-captions.scss`:
- Around line 14-16: Scope the color rule for .wp-element-caption and figcaption
to dark-background contexts only, using the existing dark-background style or
context selector. Ensure captions on light backgrounds retain their
light-context color, including future local overrides.
In `@src/scss/structural/taxonomy-filter.scss`:
- Line 40: Insert an empty line before the LS-2934 double-slash comment
following the card platform WordPress background-color declaration, satisfying
the scss/double-slash-comment-empty-line-before Stylelint rule.

Fixes - src/scss/structural/taxonomy-filter.scss: added missing blank line before the LS-2934 comment, fixing a Stylelint scss/double-slash-comment-empty-line-before violation - src/scss/structural/image-captions.scss: expanded the code comment to document the light/dark scoping tradeoff explicitly for future reviewers, no behavior change Documentation corrections - specs/002-color-contrast-fixes/data-model.md: corrected the taxonomy filter pill's state description — hover/focus-visible are changed by this feature, not unaffected - specs/002-color-contrast-fixes/quickstart.md: documented the accepted theme:validate baseline failure (pre-existing missing styles/light.json) instead of implying all three validation commands must pass unconditionally - specs/002-color-contrast-fixes/tasks.md: reverted T016 to unchecked and reworded its checkpoint — the local /blog/ run was informational only and does not satisfy the DEV verification FR-007 requires; matches the same deferred pattern already used for T009-T011 Context - All changes are corrections/clarifications responding to CodeRabbit's automated review on #61 — no functional/compiled CSS output changed - One finding (unconditional caption color scoping) was evaluated and not changed in code: confirmed via theme.json/styles/dark.json that this theme has no per-post light/dark distinction today, and the sibling taxonomy-filter.scss already applies its own dark-context tokens unconditionally — documented as a deliberate, already-recorded tradeoff rather than a defect
Context - No functional change; wording-only edit to LS-2934 entry - Needed a new commit on PR #61 to trigger CodeRabbit re-review Changed - Restructured the taxonomy-filter bullet's opening clause in CHANGELOG.md

Summary
Image captions on dark-background posts and the active taxonomy filter pill on the blog page both failed WCAG 2.2 AA color-contrast (axe
color-contrast, serious impact), flagged by the standing Playwright accessibility suite and tracked in BugHerd as task #231 under epic LS-2934.Image captions on dark-background posts
.wp-element-caption/figcaptionrendered WordPress core's unthemed default color (#555555) against this theme's active global background (#080808) — 2.68:1 contrast, below the 4.5:1 minimum. No theme.jsonelements.captionkey exists to express this in JSON, so a new SCSS partial (src/scss/structural/image-captions.scss) sets caption color using the existing--text--on-dark-mutedtoken (10.1:1 against the background), applied unconditionally. This theme runs one active global style sitewide rather than mixing light/dark per post — confirmed by checkingtheme.json/styles/dark.jsonand the siblingtaxonomy-filter.scss, which already applies its own dark-context tokens unconditionally the same way — so no per-post scoping selector is needed.The new partial is registered in
package.json's three Sass build scripts, enqueued unconditionally via the existingls_theme_get_effect_styles()/ls_theme_enqueue_effect_styles()mechanism ininc/animations.php(images/captions can appear on any page), and added tofunctions.php'sadd_editor_style()list so it also applies inside the Site Editor's iframed canvas.Active taxonomy filter pill on the blog page
.taxonomy-filter-currentpaired a blue background (--card--platform--wordpress) with light text (--text--on-dark) — 2.92:1 contrast. Swapped to the existing--text--on-lighttoken, which resolves to a dark value that clears 6.57:1 against the same background. Applied to both the base rule and its:hover/:focus-visiblestate, since that sub-rule re-asserts the identical color and would otherwise visibly revert to the failing value on hover.Both fixes reuse existing, already dark/light-paired color tokens — no new tokens were introduced.
Scope and exclusions
This PR does not address the separately-tracked broken CSS asset issue (BugHerd #233 and duplicates #235/#236/#241) or any other axe violation category — both are out of scope per the linked spec.
assets/css/image-captions.cssandassets/css/taxonomy-filter.cssare Sass-compiled build output, not hand-authored, and are excluded from manual review. Thespecs/002-color-contrast-fixes/directory (8 files) is Spec Kit planning documentation (spec/plan/research/tasks/checklists) generated ahead of implementation — informative for review context but not itself reviewable application code.Screenshots/video
No screenshots included — the visible difference is a text-color-only change (existing UI, corrected contrast on two already-shipped elements), not a new UI surface.
Accessibility notes
This PR's entire purpose is a WCAG 2.2 AA color-contrast remediation for the two elements described above. Verified via the existing
@axe-core/playwrightstanding accessibility spec (tests/specs/standing/accessibility.spec.ts) run in scopedSINGLE_PAGE_URLmode, which structurally cannot file a new BugHerd task regardless of pass/fail. DEV re-verification against the 3 caption-fix production URLs is deferred until after this PR is merged and deployed (DEV currently serves the pre-fix theme); local verification against/blog/(which exists locally, unlike the 3 caption URLs) passed with zero serious/critical violations.Test plan
