Defined in:
lib/ucode/audit/extractors/color_capabilities.rb

Overview

Color-font capability summary: which color formats a face carries (COLR v0/v1, CPAL, SVG, CBDT/CBLC, sbix) plus lightweight counts from each table’s header.

Returned fields:

color_capabilities: Models::Audit::ColorCapabilities, or nil
                    for Type 1

Counts are best-effort — any table that fails to parse yields nil for its corresponding count fields rather than crashing the audit.
