Functions
constexpr HudColor	voidfall::weaponTypeAccent (int weaponId)
	Map a weapon-type id (matching WeaponType integer order in ecs/components/WeaponState.hpp: 0=Rifle, 1=Rocket, 2=RailGun, 3=EnergyGun, 4-6=grenades) to its accent color.
constexpr HudColor	voidfall::withAlpha (HudColor c, float alpha)
	Apply alpha to a palette color (for fade-out).
void	voidfall::drawCornerBrackets (HudContext &ctx, float x, float y, float w, float h, float armLen=10.f, float thickness=1.f, float outset=0.f, HudColor color=k_amber)
	Draw four mil-spec L-shaped corner brackets around a rect.
void	voidfall::drawPanel (HudContext &ctx, float x, float y, float w, float h, HudColor fill=k_bgPanel, HudColor border=k_line, float thickness=1.f)
	Draw a Voidfall panel: solid fill + 1 px outline.
void	voidfall::drawTrailBar (HudContext &ctx, float x, float y, float w, float h, float fill01, float trail01, HudColor fillColor, HudColor trailColor=HudColor{k_tertiary.r, k_tertiary.g, k_tertiary.b, 0.45f}, HudColor bgColor=k_bgInset, HudColor borderColor=k_lineDim)
	Draw a horizontal stat bar with a damage-trail ghost (solid fill).
constexpr HudColor	voidfall::lerpColor (HudColor a, HudColor b, float t)
	Lerp between two HudColors — used to compute the visible gradient endpoint when the bar is partially filled (so the fill always represents the same slice of the underlying full-bar gradient instead of stretching to the right end).
void	voidfall::drawGradientTrailBar (HudContext &ctx, float x, float y, float w, float h, float fill01, float trail01, HudColor fillLeft, HudColor fillRight, HudColor trailColor=HudColor{k_tertiary.r, k_tertiary.g, k_tertiary.b, 0.45f}, HudColor bgColor=k_bgInset, HudColor borderColor=k_lineDim)
	Draw a horizontal stat bar whose live fill is a left→right gradient (e.g.
void	voidfall::drawKeyTab (HudContext &ctx, const char *key, float x, float y, float fontSize, float padX=3.f, float padY=1.f, HudColor bgColor=HudColor{k_quaternary.r, k_quaternary.g, k_quaternary.b, 0.45f}, HudColor borderColor=k_lineBright, HudColor textColor=k_textDim)
	Draw a bordered "key tab" pill with a single character inside.

Variables
constexpr HudColor	voidfall::k_primary {0.168627f, 0.694118f, 0.741176f, 1.0f}
	Deep panel background — opaque so HUD chrome doesn't pick up sky tint.

	Inset bar background.
constexpr HudColor	voidfall::k_lineDim {k_secondary.r, k_secondary.g, k_secondary.b, 0.7f}

constexpr HudColor	voidfall::k_textDim {k_secondary.r, k_secondary.g, k_secondary.b, 1.0f}
	Dim text — bumped luminance from ~0.55 to ~0.78 so secondary readouts (fire mode, "+reserve", "/mag", "[2] PULSAR") read clearly against the panel chrome instead of fading into it.
constexpr HudColor	voidfall::k_text {k_tertiary.r, k_tertiary.g, k_tertiary.b, 1.0f}

	Pickup amber-trim background.
constexpr HudColor	voidfall::k_typeAr = k_primary
constexpr HudColor	voidfall::k_typeSniper = k_tertiary

Detailed Description

VOIDFALL HUD design tokens — colors, sizes, and shared helpers.

Mirrors the design system from the VOIDFALL HUD prototype:

Warm near-black base, amber primary, cyan shield, warm red HP/damage.
1 px hairlines, mil-spec corner brackets on framed elements.
JetBrains-Mono-style telemetry feel (tabular numerals, all-caps labels).

Colors are converted from the prototype's oklch() tokens to linear sRGB-ish values that match perceptual intent within the existing HudColor (linear, straight-alpha) plumbing — they're rendered straight through HudContext into the existing tone-mapped HUD framebuffer, so the conversions are tuned by eye to feel right against the same backgrounds the prototype assumed.
