# Git LFS routing for large binary collateral.
#
# PowerPoint decks under docs/reports/ (seminar / work-improvement templates) are
# ~37 MB — 96% of everything tracked under docs/reports/. Routing *.pptx through
# Git LFS keeps future updates out of the packed git history.
#
# SCOPE / LIMITATION (see docs/plans/refactoring-backlog.md, Priority 3):
#   - This declaration only routes NEW or subsequently-modified *.pptx through
#     LFS. Contributors committing a .pptx need `git lfs` installed.
#   - The EXISTING committed .pptx blobs are NOT converted by this file. Actually
#     reclaiming their ~37 MB from history requires `git lfs migrate import
#     --include='*.pptx'` (a history rewrite / force-push) run in a coordinated
#     maintenance window (phase b) — it invalidates open PRs, so it is deferred.
