Processing model and limits
Match parsed plain-text leaves only, protecting Markdown code, raw HTML and links. Regex uses gu plus optional i inside deadline Worker; pattern ≤512 characters, ≤2000 matches. Insert escaped bold/mark or variable-backtick code spans; output is text, no HTML execution. Formatting boundaries are not crossed; Empty bold/code matches are counted without inserting markers; whitespace-only bold matches stay unchanged. Bold/code matches cannot cross lines; use mark for multiline matches. Each text field is limited to 32 KiB; complete output to 1 MiB. Runs in a one-second local Worker, with no network requests.
