Documentation-only changes to the quota module. The module docstring in src/quota/__init__.py was expanded with details about tokens, tokenization, pricing, and quota limits. The QuotaLimiter class docstring in src/quota/quota_limiter.py was expanded with configuration options, use cases, and behavioral details. No functional or API changes.

18-21: Tighten wording in the use-case bullet list.

Both bullet points drop key articles (“to a specific value”, “a daily basis”), which makes the guidance harder to parse. Let’s fix the phrasing for readability.

-1. When quota needs to be reset specific value periodically (for example on
-weekly on monthly basis), specify `initial_quota` to the required value
-1. When quota needs to be increased by specific value periodically (for example
-on daily basis), specify `quota_increase`
+1. When the quota needs to be reset to a specific value periodically (for example
+on a weekly or monthly basis), set `initial_quota` to the required value.
+1. When the quota needs to be increased by a specific value periodically (for example
+on a daily basis), specify `quota_increase`.

Tokens are small chunks of text, which can be as small as one character or as
large as one word. Tokens are the units of measurement used to quantify the
amount of text that the service sends to, or receives from, a large language
model (LLM). Every interaction with the Service and the LLM is counted in
tokens.
LLM providers typically charge for their services using a token-based pricing model.
Token quota limits define the number of tokens that can be used in a certain
timeframe. Implementing token quota limits helps control costs, encourage more
efficient use of queries, and regulate demand on the system. In a multi-user
configuration, token quota limits help provide equal access to all users
ensuring everyone has an opportunity to submit queries.

⚠️ Potential issue | 🟡 Minor

Correct the token description and fix comma splice.

Tokens in BPE vocabularies can span more than one full word, so saying they are “as large as one word” is inaccurate. The last sentence also needs a comma before “ensuring” to avoid a run-on. Please tighten both sentences.

-Tokens are small chunks of text, which can be as small as one character or as
-large as one word.
+Tokens are small chunks of text, which can be as small as a single character and
+may span multiple characters, including whitespace or fragments of words.

In src/quota/__init__.py around lines 5 to 17, the token definition is
inaccurate and there's a comma splice: update the token sentence to say tokens
can be smaller than a word or span multiple words (e.g., subword/BPE units)
instead of “as large as one word,” and add a comma before “ensuring” in the
final sentence so it reads “…access to all users, ensuring everyone has an
opportunity to submit queries.”
