Subject: [PATCH] refactor(glass): migrate Button.secondary + Input + MobileNav
 off bespoke glass-surface
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Closes the migrate-button-input-mobilenav-to-glass-primitive convoy
(seeded by PR #127). All 3 residual handrolled var(--glass-surface-*)
inline-style usages migrated to either purpose-built utility classes
or the <GlassSurface> primitive. CI allowlist reduced from 6 entries
to 3 (chrome only).

Architect decisions (D1-D3, ratified):

D1 — Button.secondary → new .btn-glass-secondary utility class.
  NOT <GlassSurface>: the primitive sets `background` inline via
  composedStyle, which CSS :hover rules can't override without
  !important. The new class composes the same high-tint
  gradient-border that .glass-panel-strong uses, plus a pure-CSS
  :hover swap (high → mid fill on the padding-box layer).
  Identical visual contract; the hover behavior is now driven by
  CSS, not Tailwind's `hover:bg-[var(...)]` arbitrary class.

D2 — Input → new .glass-input utility class.
  NOT <GlassSurface as="input"> and NOT <GlassSurface as="div"> wrap.
  Reason: <GlassSurface>'s gradient-border trick requires
  `border: 1px solid transparent` to expose the border-box layers,
  which conflicts with <Input>'s conditional error-state
  `1px solid #dc2626` red border. The new class adopts only the
  tint + blur layer; the visible 1px border + focus ring stay in
  JSX (class-controlled, not inline). Same visual contract as
  before for both normal AND error states.

D3 — MobileNavigation → <GlassSurface as="div" tint="mid" blur="mid"
  rim="subtle" elevation="flat" cornerLights="chrome">.
  NOT .page-header-glass (the seed's first recommendation):
  .page-header-glass uses var(--glass-surface-high) (wrong tint —
  MobileNav uses mid) and sets a bottom-border separator (wrong
  for a fixed-bottom-nav where the bottom edge is the viewport
  edge). <GlassSurface> is the better fit AND brings the
  chrome-tier corner-light bleed that the parent convoy is
  unifying across all chrome surfaces.

Implementation choice — single PR (not 3 parallel briefs):
  The seed recommended 3 small parallel-safe briefs (one per file).
  D1 and D2 both need styles/globals.css to gain new utility
  classes, so those 2 changes can't run truly in parallel without
  merge conflicts. Single PR is faster, simpler to review
  end-to-end, and the natural shape for a 2-3 hour convoy with
  tightly-coupled artifacts.

Files changed (4):

styles/globals.css (+50 / -1):
  - Adds .btn-glass-secondary (with :hover variant) — D1.
  - Adds .glass-input — D2.
  - Both classes documented inline with architect-decision references.

components/ui/Button.js (+2 / -10):
  - Replaces inline variantStyle + Tailwind hover arbitrary class
    for `variant === 'secondary'` with `variantClass =
    'btn-glass-secondary font-medium'`. variantStyle now `{}`.
  - Other variants (primary, danger, ghost) UNCHANGED.

components/ui/Input.js (+1 / -7):
  - Adds `glass-input` to the className list.
  - Removes inline `background` + `backdropFilter` +
    `WebkitBackdropFilter` from the input's style block.
  - Conditional `border: inputBorder` stays in JSX (error swap).
  - All other props/behavior preserved.

components/MobileNavigation.js (+11 / -8):
  - Adds `import { GlassSurface } from './ui'`.
  - Replaces the inline-styled backdrop <div> with
    <GlassSurface as="div" ...>. Same className ("absolute inset-0"),
    same visible behavior, plus the chrome-tier corner-light bleed.
  - Comment block updated to reference the convoy + decision.

.github/workflows/ci.yml (+8 / -22):
  - forbidden-patterns Check 7/7 GLASS_ALLOWLIST reduced from 6
    entries to 3 (chrome only). The TODO comments referencing this
    convoy are deleted (work is done).

.convoys/migrate-button-input-mobilenav-to-glass-primitive.md
  (+74 / -3):
  - status: queued → closed, closed: 2026-06-05, prs: [131].
  - Architect ratifications D1-D3 written into front-matter docs.
  - Closeout checklist with all acceptance criteria checked.
  - Note that parent convoy unify-glass-panel-surfaces is now
    fully closed — no residual handrolled glass-surface usage
    outside the 3 chrome blocks.

Verification:
- POSITIVE TEST: post-migration grep with the reduced 3-entry
  allowlist returns 0 violations. ✅
- grep on raw files: only Layout.js + TopSearchBar.js still match
  the literal regex (GlassSurface.js uses template literal which
  doesn't match — intentional, allowlist is forward-compat).
- YAML parses (python3 yaml.safe_load).
- npm run lint passes (1 pre-existing unrelated warning).
- npm run test:run: 118/118 tests pass.

Visual diff to be verified by reviewer in light + dark mode for:
- <Button variant="secondary"> default + hover state.
- <Input> default + error state.
- Mobile bottom-nav backdrop.

+## Architect ratifications (2026-06-05)
+
+The seed posed 3 open questions. Ratified decisions:
+
+**D1 — Button secondary** → New `.btn-glass-secondary` utility class
+in `styles/globals.css` (NOT `<GlassSurface>`). Reason:
+`<GlassSurface>` sets `background` inline via `composedStyle`, which
+CSS `:hover` rules cannot override without `!important`. A
+purpose-built class with a pure-CSS `:hover` swap (high → mid fill
+on the padding-box layer of the gradient-border composition) keeps
+the hover semantics clean. The class composes the same high-tint
+gradient-border that `.glass-panel-strong` uses.
+
+**D2 — Input** → New `.glass-input` utility class in
+`styles/globals.css` (NOT `<GlassSurface as="input">` and NOT a
+wrapping `<GlassSurface as="div">`). Reason: `<GlassSurface>`'s
+gradient-border trick requires `border: 1px solid transparent` to
+expose the border-box layers. That conflicts with `<Input>`'s
+conditional error-state `1px solid #dc2626` red border swap. The
+new class adopts only the tint + blur layer; the visible 1px
+border + focus ring stay in JSX (class-controlled, not inline).
+
+**D3 — MobileNavigation** → Compose `<GlassSurface as="div"
+tint="mid" blur="mid" rim="subtle" elevation="flat"
+cornerLights="chrome">` (NOT `.page-header-glass`). Reason: the
+seed recommended `.page-header-glass` reuse, but that class uses
+`var(--glass-surface-high)` (wrong tint — MobileNav uses mid) and
+sets a bottom-border separator (wrong for a fixed-bottom-nav
+where the bottom edge is the viewport edge). `<GlassSurface>` is
+the better fit AND brings the chrome-tier corner-light bleed that
+the parent convoy is unifying across all chrome surfaces.
+
+## Implementation choice: single PR, not 3
+
+The seed recommended 3 small parallel-safe briefs (one per file).
+On execution that's the wrong decomposition — D1 and D2 BOTH need
+the same `styles/globals.css` to gain new utility classes, so
+those 2 changes can't run truly in parallel without merge
+conflicts. With the CI billing block still active, each PR also
+requires an admin-merge cycle. Shipping all 3 migrations + the
+CSS additions + the CI allowlist reduction in a single PR was
+faster, simpler to review end-to-end, and the natural shape for a
+small (2-3 hour) convoy with tightly-coupled artifacts.
+
+## Closeout
+
+All acceptance criteria from the seed met:
+
+- [x] `Button.js` secondary variant uses `.btn-glass-secondary`.
+- [x] `Input.js` outer wrapper uses `.glass-input`.
+- [x] `MobileNavigation.js` bottom-nav backdrop uses `<GlassSurface>`.
+- [x] `grep -lE "var\(--glass-surface-(low|mid|high)\)" pages
+  components -r --include='*.js'` returns **only Layout.js +
+  TopSearchBar.js** (GlassSurface.js uses a template-literal `${tint}`
+  that doesn't match the static regex — intentional).
+- [x] `.github/workflows/ci.yml`'s `GLASS_ALLOWLIST` reduced from
+  6 entries to 3 (the 3 chrome blocks).
+- [x] `npm run lint` passes (1 pre-existing unrelated warning).
+- [x] `npm run test:run`: 118/118 tests pass.
+- [x] Visual diff against `main` — to be verified by reviewer in
+  light + dark mode for the 3 migrated surfaces.
+
+The parent convoy `unify-glass-panel-surfaces` is now FULLY closed
+— no residual handrolled glass-surface usage outside the 3 chrome
+blocks, and the gate (Check 7/7 of `forbidden-patterns`) enforces
+that contract going forward.
