Brave Shields blocks our bot protection mechanism (matchMedia
fingerprinting detection), causing form submissions to silently fail.
- Added getBraveErrorHtml() in SDK that returns error message HTML
- Form component renders the error when Brave is detected

## Summary
This PR adds a **Current Date** system resource, extends the `system`
object with a `pathname` property, and enhances the **Time component**
with custom date formatting capabilities to provide more flexibility and
prevent hydration errors.
### Key Features
1. **Current Date System Resource** - Provides normalized date/time
information that prevents React hydration errors
2. **System Pathname** - Adds `pathname` property directly to the
`system` object for easy access in expressions
3. **Time Component Custom Formatting** - Adds a `format` prop with
template tokens for flexible date/time display
## Motivation
These changes solve important use cases:
- **Current Date**: Prevents React hydration errors when displaying
dynamic dates (e.g., copyright years in footers). Previously, using `new
Date()` in expressions would cause server/client mismatch.
- **System Pathname**: Provides easy access to the current page path in
expressions without needing to parse the URL manually.
- **Custom Time Formatting**: Allows users to format dates with simple
templates (e.g., `YYYY-MM-DD`) without being limited to
`Intl.DateTimeFormat` options, and provides a simple way to exclude
specific date or time components to avoid hydration issues.
## Changes
### Current Date Resource
- Created
[`apps/builder/app/shared/$resources/current-date.server.ts`](apps/builder/app/shared/$resources/current-date.server.ts)
- Provides date fields: `year`, `month`, `day`, `iso`, `timestamp`
- All values normalized to midnight UTC (00:00:00.000Z) to prevent
hydration errors
- Registered in
[`rest.resources-loader.ts`](apps/builder/app/routes/rest.resources-loader.ts)
- Added to SystemResourceForm dropdown in UI
### System Pathname
- Added `pathname` property to
[`System`](packages/sdk/src/schema/pages.ts) type
- Updated [`system.ts`](apps/builder/app/shared/system.ts) to compute
and include pathname
- Normalized empty pathname to `'/'` for consistency
- Available in expressions as `system.pathname`
### Time Component Enhancements
- Added [`formatDate()`](packages/sdk-components-react/src/time.tsx:353)
function supporting template tokens:
- `YYYY`, `YY` - year (4-digit, 2-digit)
- `MM`, `M` - month (zero-padded, no padding)
- `DD`, `D` - day (zero-padded, no padding)
- `HH`, `H` - hours (zero-padded, no padding)
- `mm`, `m` - minutes (zero-padded, no padding)
- `ss`, `s` - seconds (zero-padded, no padding)
- Added `format` prop to
[`Time`](packages/sdk-components-react/src/time.tsx:386) component that
overrides `dateStyle`/`timeStyle` when provided
- Updated component logic to check for `format` prop first before
falling back to `Intl.DateTimeFormat`
- Added comprehensive tests for date formatting in
[`time.test.ts`](packages/sdk-components-react/src/time.test.ts)
- Updated component metadata in
[`time.ws.ts`](packages/sdk-components-react/src/time.ws.ts) to include
`format` in initialProps
- Example: `format="YYYY-MM-DD HH:mm:ss"` displays as "2025-11-03
18:47:25"
### Template & Fixture Updates
- Updated all CLI templates (defaults, react-router, SSG) to include
`pathname` in system objects
- Updated all fixture files (47 files total) to include `pathname` in
system objects
- All 694 tests passing
- All typecheck passing
## Usage
### Current Date Resource
Users can now add the Current Date resource from the Data Variables
panel:
1. Click + next to Data Variables
2. Select "System Resource"
3. Choose "Current Date" from the dropdown
4. Access in expressions:
- `date.year` - for copyright year
- `date.month` - current month (1-12)
- `date.day` - current day (1-31)
- `date.iso` - ISO 8601 string
- `date.timestamp` - Unix timestamp
### System Pathname
Access the current page path directly:
- `system.pathname` - current page path (e.g., `/about`, `/blog/post-1`)
### Time Component Custom Format
Use the `format` prop for custom date/time display:
```jsx
<Time datetime="2025-11-03T18:47:25Z" format="YYYY-MM-DD" />
// Displays: 2025-11-03
<Time datetime="2025-11-03T18:47:25Z" format="YYYY-MM-DD HH:mm:ss" />
// Displays: 2025-11-03 18:47:25
<Time datetime="2025-11-03T18:47:25Z" format="M/D/YYYY" />
// Displays: 11/3/2025
```
Technical Notes
- Current Date values are normalized to midnight UTC to ensure
consistency throughout the day and prevent hydration mismatches
- The pathname property is computed from the request URL and normalized
to '/' when empty
- Custom format templates in the Time component are processed before
falling back to Intl.DateTimeFormat
- All changes are backward compatible

How it works
- Cache-Control opts in caching (Cache-Control: max-age=3600)
- cached response is matched by url, method and body
- cache is invalidated with Cache-Control change
- responses stored with the cache are not replicated across regions
- responses are not shared between projects

Added react-router + cloudflare template to migrate our cloud
publishing.
This template does not support image optimization and intended only for
internal usage.
