M-5 made safeUrl() block data:image/svg+xml everywhere, including the
image-only sinks (<img src>, CSS url()) that Gallery's default images and
other SVG placeholders rely on. Loaded as an image, an SVG is rasterized
and never executes an inline <script>/onload= -- that only happens when
it's navigated to or loaded as an <iframe> document -- so M-5 over-blocked
the safe contexts and broke every published Gallery (and other components
using an SVG placeholder) using safeUrl's default images in prod.
Adds safeImageUrl(): identical javascript:/vbscript: handling to safeUrl,
but treats data: as an allowlist of image/* subtypes instead of a
blocklist -- allows all data:image/* (including svg+xml, with or without
base64), still blocks data:text/html and any other non-image data: type.
Swapped to safeImageUrl at IMAGE-src / CSS-image url() sinks only:
- Gallery.tsx img src + lightbox data-lb-src
- ImageBlock.tsx img src (toHtml)
- Logo.tsx / Navbar.tsx logo <img> src (their href/link targets keep safeUrl)
- style-helpers.ts sanitizeCssValue's url(...) handling (background-image
for HeroSimple/BackgroundSection/Section/CallToAction)
Left on safeUrl (href/iframe/form-action/navigation sinks, where
data:image/svg+xml must stay blocked): ButtonLink, Icon link, SocialLinks,
Menu/Navbar link hrefs, PricingTable buttonHref, _cta-helpers,
ContentSlider buttonHref, FeaturesGrid buttonUrl, FormContainer action
(via form-relay-wiring), MapEmbed/VideoBlock iframe src.

BlocksPanel dropped a new Image block with an explicit `src=""` prop, which
overrides ImageBlock's `src = PLACEHOLDER_SRC` default parameter (defaults
only apply when a prop is undefined, not when it's an empty string). Craft
then persisted `src:''`, and the canvas rendered a broken-image icon instead
of the placeholder.
- ImageBlock render now falls back to PLACEHOLDER_SRC whenever src is falsy
(belt-and-braces: also recovers any legacy saved src:'' state).
- BlocksPanel no longer passes src="" when dropping a new Image block, so
the craft default applies.
- ImageStylePanel now restores the placeholder (instead of blanking to '')
when the URL field is cleared.

Each component defined a .craft.related.settings panel that was never
rendered -- the right panel renders only GuidedStyles (per-type
*StylePanel components), never .related.settings. Removed all dead
settings components across every component, their settings-only helpers
(including the dead uploadToWhp/showBrowser/handleBrowse asset-browse
blocks in Logo/Navbar/VideoBlock/FeaturesGrid, and CtasEditor in
_cta-helpers), and dropped the now-empty related keys. Render output,
.craft props/rules, and toHtml statics are unchanged.

Every user-controlled URL emitted by a component's static toHtml (href,
src, action, and CSS url()) now runs through escapeAttr(safeUrl(...))
before hitting the exported HTML string, closing the XSS gaps flagged
in the A2 review (PricingTable buttonHref was fully unescaped, Gallery/
HeroSimple/ImageBlock/VideoBlock/etc. lacked scheme filtering) plus a
few more found via a grep sweep of href=/src=/action=/url( inside
toHtml template strings: MapEmbed's iframe src and the shared
form-relay-wiring fallback form action (a javascript: form action
executes on submit).

4px and 8px were imperceptible on typical image sizes. New scale
0/8/16/32/50% gives visible steps for None/S/M/L and keeps Full as
round.

Rebuilt the visual site builder from scratch using Craft.js, React 18,
and TypeScript. The new editor renders directly in the DOM (no iframe),
supports 40+ components, multi-page with shared header/footer, 16
templates, full-spectrum color/gradient controls, custom head code
injection, save/publish workflow, and auto-save.
