Module display 

Display text and public asset URL validation helpers. Public display text and asset URL validation helpers.

Aster services often expose runtime branding or UI-shell configuration such as titles, descriptions, favicons, wordmarks, and provider icons. Product crates still own the concrete keys, defaults, and visibility rules. This module only centralizes the repeated mechanics for trimming bounded display text, rejecting control characters, and validating asset URL strings that are safe to place into generated frontend HTML.
