feat(slides): bundle Inter TTFs so figures match the deck font (#109)#146
Merged
Conversation
Figures rendered in DejaVu Sans whenever Inter was not installed system-wide, making output non-deterministic across machines/CI and off-font vs the Inter deck. Bundle the Inter static TTFs (Regular/Medium/SemiBold/Bold, SIL OFL) under slides/scripts/fonts/ and register them with matplotlib via fontManager.addfont() before resolving the deck font. font.family=Inter now resolves from the repo regardless of system install; DejaVu Sans stays as the glyph-safe fallback (covers the U+2192 arrow in DF edge names). Regenerated all figures: no fallback or missing-glyph warnings.

Closes #109.
Problem
make_figures.pysetfont.family = Interbut only checked matplotlib's systemfont cache. Inter isn't installed system-wide on the dev machine / CI, so figures
silently fell back to DejaVu Sans — non-deterministic across machines and
off-font vs the Inter deck.
Fix
under
slides/scripts/fonts/, plusOFL.txt. All four report family nameInter.fontManager.addfont(...)before the deck-font resolution /rcParamsblock, sofont.family = Interresolves from the repo regardless of systeminstall.
→/ U+2192 arrow in DF edge names).Verification
findfont('Inter')resolves to the bundledslides/scripts/fonts/Inter-Regular.ttf.uv run python slides/scripts/make_figures.py— noInter not foundfallback warning,no missing-glyph warnings.
→confirmed rendering (no tofu) in the drift figures (e.g.bpi2017-drift-with-tsfm.png).
