snippet swatch helper with args

Measurements

Metric	BaselineThe benchmark measurement of the unmodified code	CandidateThe code with the proposed optimization applied	DeltaThe performance change from baseline to candidate
gzipped_client_bytes (bytes) primary	53717.000 bytes (n=1)	53941.000 bytes (n=1)	+0.41% REGRESSED
raw_client_bytes (bytes) secondary	162050.000 bytes (n=1)	161044.000 bytes (n=1)	-0.62%

Annotations

hypothesis	use a {#snippet swatch(cls,label,bordered)} called 15x — shorter call sites than each-loop and no array literal
next_action_hint	STOP trying to dedupe static markup in this bundle — both {#each} and parameterized snippets regress gz. Shift focus to ACTUALLY REMOVING content: (1) strip unused @theme tokens from layout.css that arent referenced by any utility class in source, (2) strip unused tailwind layer css, (3) delete dead @font-face weights if unused. Content removal is the only path forward for gz.
rollback_reason	+224 gz even though raw dropped 1006. Snippet with args compiles to function calls + dynamic class interpolation which gzip compresses less efficiently than repeated static markup

Base CommitThe starting commit before the optimization was applied	3c6212c633b5aae60836459a761d9ee1fd0aa283
Candidate CommitThe code with the proposed optimization applied	8d0d435ddfc96ac18ba7be30923c1728ed0ad603
