temporal-contract branding

The illustrated mascot preserves the btravstack pink beet and its original project motif: a small rounded leafless beet at the bottom of an hourglass beneath pink flow and drops. The canonical source is the website brand generator.

To refresh them, run the generator in that repository and copy the generated apps/website/public/logos/temporal-contract-{light,dark,mono,favicon}.svg files into docs/public/ as logo-light.svg, logo-dark.svg, logo-mono.svg and favicon.svg. Keep logo.svg identical to logo-light.svg as the fallback. The matching social card is docs/public/og-temporal-contract.png (1200 × 630), rendered from the editable social-card template with ?project=temporal-contract.

The README, documentation navigation and hero select a mark for the reader's color scheme. The monochrome variant preserves the illustration in grayscale and supplies the decorative CSS mask. A dedicated variant serves as the favicon. All assets are committed locally so documentation builds and deployed pages remain independent of the website repository. The docs configuration applies the current deployment base to favicon and social-card URLs, including prerelease deployments.
