Catches the mistakes coding agents repeat before they merge: a pull-request gate with no model call and no API key.
Short answer: Scope blur >=40px to md:/lg: desktop viewports. A large blur is painted on the GPU for every frame. Phones drop frames and heat up.
Group: UI and mobile performance. Status: stable. Generated from the rule definitions; do not edit by hand.

Mobile GPU budget: scope blur >=40px to md:/lg: desktop viewports.

dev_rules.scan_added_lines); brevio-core scan does not run it.dev_rules.slice_micro_rules).A person can silence one finding with brevio-core: ignore R1.1 -- reason on the line or the line above. Without the reason it does not count. An agent cannot silence it: the agent hook and the MCP tools never honour the comment, and a pull request that adds one is reported until a reviewer allows it. Fixing the code is still the better answer.
What the scanner already leaves alone: A line that already scopes the blur with a sm:, md:, lg:, xl: or 2xl: prefix is not flagged.
A scan reads only the lines you add, so a line that was already in the file is not flagged.
To change what the rule flags, edit its definition in dev_rules.py or code_rules/__init__.py. That is a code change and is reviewed like one.
