fix(web-shared): make encrypted-data blur backwards compatible with Tailwind v3

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

8633ebb9b32f28cce4344329840aca47e22d3197

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

8633ebb9b32f28cce4344329840aca47e22d3197

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

8633ebb9b32f28cce4344329840aca47e22d3197

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

8633ebb9b32f28cce4344329840aca47e22d3197

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

8633ebb9b32f28cce4344329840aca47e22d3197

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

8633ebb9b32f28cce4344329840aca47e22d3197

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:

8633ebb9b32f28cce4344329840aca47e22d3197

[mitul-s]

Description

The encrypted-data preview on the run detail panel (EncryptedDataBlock in packages/web-shared/src/components/sidebar/copyable-data-block.tsx) was using the blur-xs utility class. That utility only exists in Tailwind v4 — consumers of @workflow/web-shared who are still on Tailwind v3 see no blur at all on the placeholder, defeating the visual treatment of the encrypted state.

This swaps blur-xs for the arbitrary-value utility blur-[4px] (4px matches v4's blur-xs). Arbitrary values have been supported in Tailwind since v3.0's JIT engine, so the class compiles to filter: blur(4px) on both v3 and v4.

How did you test your changes?

Visual inspection of the decrypt card on the run detail panel — the [encrypted] placeholder still renders blurred and the Decrypt button overlay is unchanged. No JS/CSS behavior change for v4 consumers.

No backport to stable for 8633ebb (AI decision).

The EncryptedDataBlock component being fixed does not exist on stable — that file's stable version has no blur-xs usage and no encrypted data preview. This fix builds on main-only behavior, so there is nothing to backport.

To override, re-run the Backport to stable workflow manually via workflow_dispatch and paste this commit SHA into the ref input:
