/**
 * Lazy chunk entry: the colored file-icon theme dataset — brand and generic
 * glyphs paired with their display color (extensions / exact file names /
 * directory names), consumed by `registerColoredFileIcons` in the core half
 * when the user turns the theme on.
 *
 * Data provenance: the tables below come from PR #429 (@fenter,
 * `feat/file-type-icons`, the 563-entry table); they are reused here as the
 * plugin's built-in OPTIONAL icon theme. The case-variant folder keys
 * (`Android`/`android`, `IOS`/`ios`) were folded into one rule because the
 * resolver matches names case-insensitively.
 *
 * Why a chunk: ~160 react-icons glyphs (Simple Icons brands + VSCodicons) and
 * ~700 lines of table would otherwise sit in the startup bundle for a theme
 * most users never enable. The core half only fetches this on demand.
 *
 * Skin contract: this module is the ONE documented exception to the
 * token-only rule (guide §12) — brand colors are identity, not chrome, and
 * the theme is opt-in, so they cannot ride `--dsw-alias-*`. Nothing here is
 * imported by the core bundle; keep it that way.
