  <p class="coverage-chart-note">Each count is one feature on one provider, across {{ coverage.summary.feature_count }} shared feature rows. The outlined bar counts verified provider offerings within RubyLLM's scope. Filled bars count built-in RubyLLM support; usable raw options and partial integrations are listed separately in the matrix. Unverified offerings, realtime conversations, and provider-stored conversation lifecycles are excluded. These selected features do not represent a complete API inventory.</p>
