S7-backed cache metadata (CacheMeta)

Usage

CacheMeta(family_id = character(0), source = character(0), files = list())

Arguments

family_id: (character(1)) A non-empty safe identifier for the font family. Allowed characters: letters, digits and hyphen (no spaces, slashes, dots, colons, tildes, etc.).
source: (character(1)) Name of the provider or source that produced the cached font files.
files: (list(1+)) A non-empty named list of file paths. Names are weight identifiers (e.g., "400" for normal weight 400, "400italic" for italic weight 400). Each element is a character(1) path to the local font files.

Value

(S7_object) A validated S7 CacheMeta object.

Details

The added property is a getter-only field that returns the current timestamp as a character string when accessed. It cannot be set during construction.

Weights are not explicitly stored - they are derived from the names of the files list. Registration functions are responsible for selecting appropriate weights for regular/bold variants.
