Side B fixes a real off-by-one/indexing bug (thread_post_index semantics), removing a fallback that masked an invariant violation with .expect() and documenting the 0-based vs 1-based confusion, plus adds regression tests asserting correct index values. Side A is purely cosmetic: dedenting HTML markup and tweaking CSS counter styling across theme files, which is low-risk but non-functional churn.

council reasoning
B fixes a real indexing bug (1-based/unwrap_or(0) vs 0-based /t/tag/N routes), enforces the invariant with expect, always emits correct post links, and adds integration assertions. A only unwraps a vote-compare shell div and tweaks ranking-number CSS—cosmetic churn with little lasting design impact.
Side B fixes the semantics of `thread_post_index` by making rank history use the actual 0-based thread index consistently, replacing a silent `unwrap_or(0)` fallback with an `expect` that enforces the invariant, updating rendering to always generate the post link, correcting documentation, and adding integration tests for the behavior. Side A is largely a presentation change: it removes a wrapper element from the compare page and adjusts CSS styling for ranked lists across themes, with little impact on core functionality.
