arxiv-keymaps: drop trumpet/ocarina silhouettes from asymmetric figure
The bare silhouettes were "decorative" — they didn't actually depict
the asymmetry the caption claimed they showed (valve semitone offsets
for trumpet, finger-hole positions for ocarina). The user flagged
this as inaccurate after rendering the page out and looking at it.
Cleanest fix: drop them. Keep the guitar EADGBE + violin GDAE
tuning panels, which DO directly show their asymmetric/uniform
interval structure as labeled string diagrams. Caption still names
trumpet and ocarina in prose as members of the same family; the
genealogy paragraph above continues to carry their lineage.
Removes:
- papers/arxiv-keymaps/trumpet.png (CC0 silhouette, no longer used)
- papers/arxiv-keymaps/ocarina.png (CC BY 3.0 silhouette, no longer used)
- references.bib entries for both

\caption{Asymmetric pitch interfaces across instrument families. \textbf{Top}: trumpet (left), valves produce non-uniform semitone offsets $-2, -1, -3$ from open; ocarina (right), finger holes cluster asymmetrically across the body. \textbf{Bottom}: guitar (left), 6-string EADGBE is uniform P4 \emph{except} the M3 between G and B; violin (right), strict P5 between each string but each is a different absolute pitch. The standard piano keyboard is one member of this larger family in which the physical-to-pitch interface is irregular by design --- the diatonic naming keymap embodied in many surfaces, each with its own asymmetry.

\caption{Two stringed-instrument tunings as a small case study in asymmetric pitch interfaces. Guitar EADGBE is uniform in perfect fourths \emph{except} the major-third between G and B (the irregularity that lets the standard chord shapes lie under the hand and that the entire literature of folk, blues, jazz, and rock guitar has been authored against). Violin keeps strict P5s but each open string is a different absolute pitch. Trumpet (3 valves with non-uniform semitone offsets), ocarina (asymmetrically clustered finger holes), and the standard piano all belong to the same family: the diatonic naming keymap embodied in many surfaces, each with its own asymmetry.}
