• Initialize string builder size based on filesize?
• Review whitespace handling code
• Add leak checks for public procs.
• Simplify trim_standalone_whitespace — four temp arrays (li_buf, ri_buf, left_done, right_done) could potentially be reduced to two by merging the done-tracking into the index buffers using sentinel values (e.g. -2 = already trimmed).
• Adjacent standalone tags don't capture indent for the second tag (e.g. {{>a}}\n {{>b}} — {{>b}} gets indent="" because its left text was consumed by {{>a}}'s right-trim). Blocks recover via deindent_blocks, but partials/parents have no fallback.
• lazy load partials ? (with mutex)
