Re-walked the glyph path a 4th time; confirmed ammo digits use the same
textrelated.c path (gunfire.c:5906 -> textRender -> textRenderGlyph), no
separate HUD-number renderer. Same contradiction as M-6/7/8: every stage
runtime-verified non-mirrored, glyphs still X-flip. Needs RenderDoc or the
asymmetric-texel experiment, not another static trace.
New finding: gfx_pc.cpp:1546/1551 D74 wrap-block is dead code (cms &
G_TX_WRAP with G_TX_WRAP==0) + OOB vertex-vs-texunit array index. Latent,
logged not fixed.
New docs/GRAPHICS-BACKLOG.md collects all cosmetic items (D74/D75/D76/
D77/D114/D116) below level-progression + crash priority per user.
