Closes #1041.

npx tsc --noEmit gives 14 errors on main, this takes it to 0. Three unrelated causes:

AcidSquares (4 errors) — rtA/rtB are RenderTarget | null and ensureTargets() fills them in, but tsc can't see through the call. The two lines right below each render() already use rtA!/rtB!, so the render calls were the odd ones out. Made them match.

SpecularButton (2) — the null check goes through an intermediate steer boolean, and narrowing doesn't survive that. Inlined the condition into the ternary. Same operands in the same order, so nothing changes at runtime.

SplitText (8) — this one's the cast itself, which is why I called it out. tag is already typed 'h1' | ... | 'span', and as React.ElementType widens that to every intrinsic element. JSX intersects props across a union, so with input, svg and friends in there, children/ref/style/className all collapse to never. That's exactly the 4 errors per file. Dropping the cast fixes it, and the type ends up more precise than the cast was.

Ran npx vite build after, still builds (13.3s).

Two things I deliberately left alone:

  • The JS variants don't need matching changes. All 14 are type-only — ensureTargets() does populate the targets, steer does include the null check, and the 8 tags do accept those props. Mentioning it because of the four-variants rule in CONTRIBUTING.
  • prettier --check already fails on both SpecularButton.tsx files on main. Running --write pulls a bunch of unrelated reformatting into the diff, so I left it.

AI was used for assistance.

- Change texts: string[] to texts: React.ReactNode[] in TS variants
- Move   separator inside the span (encapsulated in scroller)
- Replace numCopies! non-null assertion with numCopies ?? 6
- Update prop table description in demo to reflect ReactNode support
- Applied consistently across all 4 variants (JS-CSS, JS-TW, TS-CSS, TS-TW)

This is a non-breaking change — plain strings are valid ReactNode values,
so all existing usage continues to work. The change unlocks rich content
like icons, styled spans, gradients, and mixed JSX in the scrolling ticker.
Problems in the original:
- Single useEffect with all 22 props as dependencies caused a full WebGL
  context teardown and canvas remount on every prop change — GPU pipeline
  rebuilt from scratch for something as minor as a color tweak.
- requestAnimationFrame ran unconditionally at 60fps even when the element
  was scrolled completely offscreen, burning GPU cycles with no visible output.
- No awareness of browser tab visibility — shader kept executing even in
  background tabs.

Changes (applied to all 4 variants: JS-CSS, JS-TW, TS-CSS, TS-TW):

1. Split into two useEffects:
   - Effect 1 ([] deps): creates renderer, canvas, geometry, program, mesh
     exactly once for the lifetime of the component.
   - Effect 2 (prop deps): writes directly to uniform values — zero GPU cost,
     no context recreation, no canvas remount.

2. WeakMap<HTMLDivElement, GrainientCtx> bridges the two effects without
   creating strong references that would leak on unmount.

3. IntersectionObserver (threshold: 0) pauses the RAF loop the moment the
   canvas scrolls offscreen and resumes when it re-enters the viewport.

4. visibilitychange listener pauses the RAF loop when the browser tab is
   hidden and resumes when the user returns to it.

Result: no unnecessary GPU work, dramatically lower CPU/GPU usage on pages
where the component is not in view, and instant prop updates without flicker.

Adds a new animated hexagonal grid background component, as requested
in DavidHDev#854. Built using the same canvas-based rendering pattern as the
existing Squares component.

Features:
- Flat-top hexagonal grid with seamless tiling animation
- 5 direction options: right, left, up, down, diagonal
- Configurable hex size, border color, and hover fill color
- Smooth animation via requestAnimationFrame
- Mouse hover detection with hex-coordinate mapping
- Radial gradient overlay matching existing backgrounds
- Responsive canvas with resize handling

Includes all 4 component variants (JSX, JSX+Tailwind, TSX, TSX+Tailwind),
demo page with customization controls, and code constants.

Closes DavidHDev#854
Reworked based on owner feedback — instead of a separate Hexagons
component, extends the existing Squares component with a `shape` prop
that supports 'square' (default) and 'hexagon' variants.

Changes:
- Added `shape` prop ('square' | 'hexagon') to all 4 component variants
- Hexagon mode uses flat-top hex grid with proper tiling geometry
- Seamless animation wrapping for both shapes
- Hover detection adapts to hex coordinate mapping when in hexagon mode
- Added Shape toggle (Square/Hexagon) to demo customization panel
- Updated usage example in code constants
- Fully backward compatible — defaults to 'square'

Closes DavidHDev#854

AcidSquares passed rtA/rtB straight into renderer.render(), which takes
RenderTarget | undefined, while the two lines below already assert the
same values with !. Made the two render calls consistent with them.

SpecularButton computed the null guard into an intermediate boolean, so
narrowing did not reach pointerAngle at the use site. Inlined the same
condition into the ternary; runtime behaviour is unchanged.

SplitText widened tag to React.ElementType, which is a union over every
intrinsic element. JSX intersects the props of a union, and the
conflicting attribute types across that union collapse children, ref,
style and className to never. tag is already a union of eight tags that
all accept the same props, so dropping the assertion both typechecks and
keeps the type more precise than the assertion did.
