Summary

Brand refresh: FileKit's visuals are now code instead of Figma exports, so they can be edited and re-rendered from the repo.

• brand/ holds the sources: a WebGL silk gradient shader, an HTML hero layout (Inter Bold Italic title drawn twice in overlay, Inter Regular subtitle, construction lines), a new mark, and palette.json as the single source of colors.
• npm run render (Playwright) exports every asset. npm run preview serves the sources and a brand board to tweak them live. See brand/README.md.
• New mark: a file sheet with a folded corner, slanted at Inter Bold Italic's 9.4° italic angle so it leans like the "F". The leaf icon in the docs was Mintlify's default, not a FileKit logo.
• Palette: green into gold, a warmer take on the FileKit green.

This PR only adds assets. README and docs still point at the old images; the rewiring is a separate change.

Exported assets

Asset	Path
README hero (1920×960)	brand/exports/readme-hero.webp
GitHub social preview (1280×640)	brand/exports/social-preview.jpg
Docs hero (1920×1080)	docs/brand/hero.webp
Open Graph image (1200×630)	docs/brand/og.jpg
Logo, light / dark backgrounds	docs/brand/logo-light.svg, docs/brand/logo-dark.svg
Favicon	docs/brand/favicon.svg
Mark (512×512)	brand/exports/mark.svg

Heroes are lossy on purpose: the film grain makes lossless PNGs about 3.5 MB each. They are WebP where the rounded corners need transparency, and JPEG for social cards (GitHub caps the social preview at 1 MB). Only the dark hero is exported for now; a light variant exists in the sources.

Palette for docs/docs.json

Key	Hex
colors.primary	#1A7F4B (white text on it: 5.0:1)
colors.light	#E3C266
colors.dark	#1A7F4B

Affected platforms

None. No library code changes.

Validation

• Ran npm run render locally; every asset was regenerated, then checked visually on the brand board (npm run preview).
• Logo SVGs checked on light and dark backgrounds, and the favicon at 16 and 32 px.
• No Gradle tasks needed: no Kotlin changes. CI does not build these assets.

Follow-up

• Rewire README and docs to the new assets (hero, logos, favicon, OG image, palette).
• Upload brand/exports/social-preview.jpg in the repository settings (manual step).

Walkthrough

The pull request adds FileKit brand palette and visual sources, a hero page and background renderer, commands to render and preview assets, and a page that displays brand materials.

Changes: Brand assets

Layer / File(s)	Summary
Palette and visual primitives brand/palette.json, brand/src/mark.js, brand/src/background.js, brand/README.md	The palette defines documentation, mark, and background colors. The mark module generates SVG shapes. The background module paints seeded gradients with WebGL2.
Hero composition brand/src/hero.html, brand/README.md	The hero page loads palette settings, paints a background, positions title and subtitle text, and draws construction guides. It reads theme, rounded-corner, and seed values from URL parameters.
Asset rendering and preview brand/package.json, brand/.gitignore, brand/fonts/OFL.txt, brand/render.mjs, brand/README.md	The package adds render and preview commands and development dependencies. The renderer creates SVG assets and captures hero images through Chromium. Preview mode serves files from the brand and documentation brand directories.
Brand board brand/src/board.html	The board displays brand images, logos, favicons, and palette swatches.

Merge Risk: Minimal · up to 6ea10

The change adds local brand asset generation and preview. No merge-blocking risk is established.

Security architecture risk: Low · up to 6ea10

The preview service accepts connections only from this computer, and asset output paths are fixed. Its directory restriction is weaker than its stated boundary, however. Exposure depends on local files and links; no sensitive-file disclosure was demonstrated.

Retained concerns

• Low · security · inferred: The new preview server does not fully enforce its stated brand/ and docs/brand/ read boundary. Its string-prefix allowlist would accept matching-prefix sibling paths, and readFile follows symlinks beneath allowed paths. Disclosure outside the intended roots is conditional on workspace contents; no such target was demonstrated, and the server binds only to loopback.

Security review details

Security Blast Radius

• inferred — The evidenced exposure is a developer-machine loopback file service, not a remotely bound production endpoint. Any successful unintended file read would use the renderer process's filesystem permissions; no tenant, cloud identity, or service credential transition is shown in this flow.

Security Findings and Attack Paths

• inferred — A client able to reach the loopback listener could request an existing matching-prefix sibling file or follow an existing served-root symlink outside the intended directories. This is a conditional containment concern, not demonstrated arbitrary or sensitive-file disclosure. The inspected source roots contained no such escape target.

Trust Boundaries and Controls

• observed — Loopback binding and an explicit two-root allowlist constrain the file-serving boundary. Separately, hero URL parameters select presentation settings and a numeric seed; they do not select shader source, filesystem destinations, or privileged operations in paintBackground.

Resilience and Maintainability Implications

• inferred — Normal rendering closes each page, then the browser and server. Rejections bypass those explicit cleanup calls, but the render invocation is awaited at module scope without recovery. Source inspection therefore establishes incomplete orderly cleanup, not a listener proven to remain available after fatal process failure.

Hardening Proposals

• proposed — Enforce directory membership on canonical paths, with an explicit symlink policy, rather than accepting string-prefix matches. This would make file authority match the server's stated two-directory boundary.

Full details: Title check

Explanation

The title "🎨 Add brand visuals as code" matches the main change. The PR adds a brand/ directory with editable brand sources (WebGL silk-gradient shader, HTML hero layout, mark, palette.json), render and preview scripts, and exported assets. The emoji is a minor style choice and does not hide the primary change. The title is short, specific, and readable in history.

Full details: Docstring Coverage

Explanation

Docstring coverage is 83.33% which is sufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 6 functions across 3 files.

Inline comments:
Review comments at @brand/render.mjs:
- Line 102: Update the “Live hero” URL in the console output to remove the
hard-coded seed parameter, so the preview uses the configured palette seed by
default while editors can still add a seed override manually.

Review comments at @brand/src/hero.html:
- Line 75: Update the hero layout and rendering flow around the cqw measurement
so resizing the viewport recalculates the grid and guides and redraws the canvas
at its new dimensions, rather than stretching the previous image. Preserve the
existing initial-render behavior.

⚠️ Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.

Delete the vertex buffer during cleanup.

gl.createBuffer() allocates a new buffer on every paintBackground call, but this block deletes only shaders and the program. The hero invokes paintBackground from its resize handler, so resize bursts defer buffer release to garbage collection and can create avoidable WebGL resource pressure. WebGL guidance recommends eager deletion. (raw.githubusercontent.com)

Store the buffer in a variable and call gl.deleteBuffer(buffer) after drawing.

Proposed fix

-  gl.bindBuffer(gl.ARRAY_BUFFER, gl.createBuffer());
+  const buffer = gl.createBuffer();
+  gl.bindBuffer(gl.ARRAY_BUFFER, buffer);
...
   gl.deleteProgram(program);
+  gl.deleteBuffer(buffer);
