hfApplyStageConfig (Block B, verbatim across all 5 retrofitted caption identities) only ever set --hf-caption-primary/--hf-caption-accent when the corresponding brand.primaryColor/accentColor key was present, with no else branch to clear it when absent. Re-attaching a brand-less payload after a branded one left the custom property (and any JS-cached color derived from it, e.g. caption-pill-karaoke's hfColorActive and caption-emoji-pop's hfAccentColors) stuck at the stale value instead of reverting to the CSS fallback, violating idempotent re-attach. Also removes caption-editorial-emphasis's dead .word--italic CSS rule and CLASS_MAP.i entry — hfMakeBlocks only ever emits "n"/"e" tags, "i" was only reachable via the old hand-authored BLOCKS literal this task replaced.
