      "summary": "Formats a Brazilian phone number with one of several masks.",
      "description": "Formats a phone number according to Brazilian patterns.\n\n- `options.mask` (default `sn`) picks the pattern: `sn` (subscriber number only, 9 digits: `98765-4321`), `nanp` (DDD plus number, `(11) 90000-0000`, 11 digits for a mobile and 10 for a landline, any other length keeps the 11-digit grouping), `e164` (`+5511987654321`), `international` (`+55 11 98765-4321`), `service` (`0800 123 4567`, `4004-1234`) and `auto`. An unknown `mask` falls back to `sn`.\n- If the value includes a DDD, pass `{ mask: \"auto\" }` or `\"nanp\"`: the default `sn` mask assumes no DDD and truncates one (`11900000000` gives `11900-0000`).\n- `auto` picks `service` for a service number, `international` when the value carries a country code, otherwise `nanp` for more than 9 digits and `sn` for the rest.\n- `e164` and `international` first drop a country code in the input, as `phone.parse` does, and fall back to `service` for a service number. `e164` keeps at most the 11 national digits, as `international` does (`119888877660000` gives `+5511988887766`). Until 2.4.0 `e164` kept them all.\n- `sn` and `nanp` drop an explicit `+55` or `0055` too, so `+5511987654321` gives `(11) 98765-4321` under `nanp`. Until 2.4.0 it gave `(55) 11987-6543`. A bare `55` stays, since it may be the DDD (`5511988887777` gives `(55) 11988-8877` under `nanp`).\n- A number still being typed after an explicit country code is formatted as far as it goes (`+55 11 9` gives `+55 11 9` under `international` and `auto`, `+55119` under `e164`). The value `+55` alone returns an empty string.\n- `options.obfuscate` (default `false`, read for truthiness) hides the subscriber number with `*` under every mask. It keeps the prefix that names a region or a service (the DDD, `+55`, the `0800`-like code, the `300X`/`400X` root) and the last 2 digits the mask has room for: `(11) *****-**21`, `0800 *** **67`, `4004-**34`. This is a convention of the library, not an official rule. It keeps the count of the gov.br account, which shows only the last 2 digits of a mobile. The DDD stays visible, although gov.br hides it.\n- With the default subscriber-number mask, a DDD-prefixed value is truncated before it is obfuscated, so the visible pair is not the last 2 digits of the input (`11987654321` gives `*****-**43`). Pass `{ mask: \"auto\" }` when the value has a DDD.\n- Under the `service` mask with `obfuscate`, a value that is only a service prefix so far keeps it (`0800` stays `0800`), since the prefix names a service, not a subscriber. A value too short to be recognized (`080`) is fully hidden (`***`). A value that is not a service number becomes one `*` per digit, which hides the digits but not how many there were.\n- With `obfuscate`, a valid 3-digit public utility code (`190`) is returned as it is under the `service`, `auto`, `e164` and `international` masks. The `sn` and `nanp` masks read it as an ordinary short number and hide it.\n- Under `e164` with `obfuscate`, the digits after the 11th national digit are dropped. This affects only invalid input.\n- A number is read only when it is a safe non-negative integer. A negative, fractional, non-finite or unsafe number returns an empty string (2.4.0 read the digits of any number).\n- Pending decision (findings §2 #4): the reference (JS) defaults to the subscriber-number mask, which truncates a DDD-prefixed number. The other libraries default to `(11)99402-9275`.",

The function checks only the structure: the number does not have to be assigned to anyone.\n\n- A country code (`+55`, `0055` or a bare `55`) is accepted and removed first, as in `phone.isValid` with `accept: [\"service\"]`: `+55 0800 123 4567` is valid. Until 2.4.0 it was rejected. A bare `55` is removed only when 11 digits that form a service number are left (`5508001234567` is valid; `55190` and `5540041234` are not).\n- Any character other than digits, whitespace and `()+.-/` (a letter, for instance) makes the value invalid. Until 2.4.0 such characters were dropped, so `abc190` was valid.\n- Códigos Não Geográficos `0300`, `0303`, `0500`, `0800` and `0900` followed by 7 digits (11 in total; the old 6-digit form, such as `0800 123456`, is rejected). The rule of `0500` that encodes a donation amount in the last two digits is not enforced.\n- The abbreviated `300X`/`400X` numbers (8 digits). Other carrier prefixes are rejected.\n- The 3-digit public utility codes designated by Anatel (such as `190` and `192`), from Anatel's current SUP list and the Anexo of Ato nº 43.151/2004. `112` is accepted: the current SUP list has it (2.4.0 rejected it).\n- `911` stays rejected. The SUP list names it next to `112`, but Resolução Anatel nº 749/2022, art. 13, gives public utility services only the `1N₂N₁` range. The two official texts conflict, so the 2.4.0 answer stays.",

Until 2.4.0 the length rule below applied to the explicit forms too, so `+55 11 9` gave `55119`.\n- A bare leading `55` is stripped only when 10 or 11 digits are left (DDD plus an 8 or 9 digit subscriber number). This way area code 55 is not mistaken for a country code: `55987654321` is kept, and `55 11 9` gives `55119`.\n- A number is read only when it is a safe non-negative integer. A negative, fractional, non-finite or unsafe number returns an empty string (2.4.0 read the digits of any number).",
