It balances vintage aesthetics with modern UI patterns, featuring a stark 'chiaroscuro' effect where selected elements pop with brilliant white against a deep, shadowed background. Perfect for storytelling-driven applications or themed dashboards.

Frequently Asked Questions
How is the 'chiaroscuro' lighting effect technically implemented for selected dates to ensure visual pop without degrading text legibility?
The component utilizes a combination of 'box-shadow: 0 0 20px rgba(255, 255, 255, 0.6)' and 'background: #FFFFFF' on the active day cell. To maintain legibility, the text color is programmatically flipped to a deep charcoal (#1A1A1A) using a CSS transition on the 'color' property, while a 'mix-blend-mode: screen' is applied to the container to simulate light bleeding from a desk lamp.
What CSS method is used to apply the film grain texture without impacting the performance of the responsive grid layout?
The film grain is achieved through a persistent '::after' pseudo-element on the main container with a 'pointer-events: none' attribute. It uses a base64-encoded SVG noise filter as a 'background-image' with 'opacity: 0.04'. This ensures the texture sits above the 'Special Elite' typography without triggering constant re-paints during window resizing.
How does the 'Case-file Header' handle dynamic date ranges while maintaining its specific 'typewritten report' aesthetic?
The header employs a 'grid-template-areas' layout that anchors the 'Special Elite' month label and 'Playfair' year indicator. It uses 'text-decoration: underline' with a custom 'text-underline-offset' to mimic manual typewriter underscores. When a range is selected, the component uses a '::before' pseudo-element to render a 'stamp' effect using 'transform: rotate(-5deg)' and a semi-opaque red 'border-image'.
Can the hover-invert navigation effects be adjusted for high-motion sensitivity users while keeping the film noir theme?
Yes, the component supports a 'prefers-reduced-motion' media query that replaces the 300ms 'filter: invert(1)' transition with an instantaneous opacity shift. The 'hover-invert' logic specifically targets the SVG arrow paths, swapping the 'fill' attribute between #FFFFFF and #000000 to maintain the high-contrast aesthetic without the kinetic slide effect.
In a scenario requiring a 'Top Secret' classification, how can the component be modified to redact specific unavailable dates?
Developers can pass an 'isRedacted' boolean to the 'dayRenderer' prop. When true, the component applies a solid 'background-color: #000000' over the cell and uses a '::before' block element to simulate a thick ink stroke. The 'pointer-events' are disabled for these cells, and the 'aria-label' is updated to 'Classified' to ensure screen readers convey the thematic restriction.
