How to use these pages

Each page is a single standalone markdown file documenting one CEF header. The page begins with the header name and an overview, then has one ## section per interface declared in that header. Each interface section lists:

• Source File — the CEF header path
• Process / Thread Context — verbatim from the header comment
• Purpose — one or two sentences from the header comment
• Methods — every public method with Parameters, Return Value, Usage Instruction, and Threading Constraint
• Usage Example — a cpp code block grounded in the actual API signatures

Where the source header does not specify a threading constraint, the page explicitly says "Threading constraint not specified in source." — these docs never guess.
