Render the three per-note teaching marks on both highways, mirroring the
bend-curve render (#532). Display only — no scoring / NoteVerifier coupling.
- 2D static/highway.js: fg renders by default as a small finger numeral hugging
the gem (T = thumb, 1..4); sd (degree label) and ch (strum bracket connecting
notes that share a ch key, arrow direction from pkd) are opt-in behind a new
`showTeachingMarks` toggle (exposed via toggle/get/set + the bundle's
`teachingMarksVisible` flag). Pure helpers teachingFingerLabel /
teachingDegreeLabel / strumGroupBuckets drive the glyphs. ch bracket is
note-stream-only (chord notes already read as one gesture).
- 3D plugins/highway_3d/screen.js: fg (default) + sd (opt-in, mirrors the 2D
toggle via bundle.teachingMarksVisible) render next to the per-note fret label
via a new pooled sprite (pTeachMarkLbl); _scrChordNote resets fg/sd so chord
notes don't inherit stale marks. ch strum brackets are deferred in 3D (no
cross-note batch pass in the per-note render); 2D covers ch.
Tests: tests/js/highway_teaching_marks.test.js extracts the pure helpers from
both files (extract-and-eval) and asserts label mapping + strum-group bucketing.

Post-merge Codex review of the bend-curve PRs (#531/#532) surfaced edge cases:
- GP8 (#531 P2): bnv timing used rn.sustain, which is zeroed for notes <= 0.2s,
so short GP8 bends kept the scalar bn but lost bt/bnv. Use the beat duration
`dur` (matching the GP5 path) so the curve survives.
- 2D highway (#532 P2): bnvNormalizedPoints mapped x over the curve's own t-range
[first,last] instead of the note span, so curves not starting at 0 / ending at
sus were time-distorted. Now maps over [0, sus] (clamped), with a curve-span
fallback when sus<=0 (existing no-sus callers unaffected).
- 3D highway (#532 P3): the sustain ribbon + bend chevron were gated on bn>0, so a
note carrying an authoritative bnv with bn==0 drew no ribbon/marker. Both now
also fire on bnv presence; chevron steps derived from max(bn, bnv peak).
Codex-reviewed: clean (no findings). +1 JS test (sus-relative mapping + fallback).
JS 8/8, 250 core GP/song tests pass.
NB: GP8's short-bend path still lacks a dedicated synthetic-GPIF fixture (same gap
as the GP8 offset-prop-names P3) — _gpx_bend_shape units cover the function; the
fix is the one-line caller change.

PR-B of the bend-shape feature (feedpak §6.2.1). Both highways drew a bend
from the scalar `bn` only; now they trace the authoritative `bnv` curve
([{t, v}]) when present and fall back to the `bn` arc/envelope otherwise.
2D (static/highway.js drawNote): when a note carries `bnv`, draw the real
shape as a contour above the gem (round-trip rises then falls, pre-bend
starts high, release descends — `bt` is implicit in the point shape), with
an arrowhead only when the gesture ends rising. `bnvNormalizedPoints` maps
{t,v} to a 0..1 x span. The scalar-arrow path is preserved unchanged as the
fallback; the peak label is unchanged.
3D (plugins/highway_3d/screen.js): `bnvSampleAt` linearly interpolates the
curve (clamped to its endpoints) and `bendSemisAtTime` samples it when
present, else keeps the synthetic rise→hold→release envelope from `bn`. The
chevron count still comes from the peak. Fixed a stale-scratch hazard: the
reused `_scrChordNote` now resets `bnv`/`bt` (omit-when-default) after
Object.assign, mirroring the existing `fhm` reset, so a chord note without a
curve can't inherit the previous note's contour.
Render-only — no wire/schema change. Pure helpers covered by
tests/js/highway_bend_curve.test.js (interp, clamping, round-trip,
degenerate/empty); node --check passes on both files; full tests/js green.

Reword comments/docstrings/strings and rename identifiers that referenced
the external game and its file formats:
- format-id "psarc" -> "archive"; local vars psarc_path -> song_path,
psarc_base -> tone_base
- lyrics provenance value "sng" -> "notechart" (legacy "sng" still accepted)
- highway_3d fret-ghost scope value "rocksmith" -> "chords" (invalid/legacy
values fall back to the default, preserving behaviour)
- neutralise references in prose, test names/data, .gitattributes and docs
No functional change beyond the renamed identifiers; all Python compiles.
