Rename the editor entry-point files and React identifiers to match the new project name. Files moved from CaracasEditor[.tsx|.css] and CaracasFileEditor.tsx to their Slidewise equivalents; CSS class names, public exports, and the tsconfig include list follow.
Update the package name, HTML title, built CSS asset filename, localStorage key, default file extension, log prefixes, data attributes, and inline comments to match the new project name. No behavior changes.
Substantial fidelity overhaul for imported PPTX decks. The previous
importer ignored theme colors, slide layouts/masters, and grouped
shapes — meaning anything that inherited style/position from a layout,
used a theme color, or sat inside a group lost its formatting.
* Theme colors. Walk slide → layout → master → theme rels and resolve
schemeClr tokens (accent1..6, bg1/bg2, tx1/tx2) using the loaded
a:clrScheme. Apply lumMod/lumOff/shade/tint/alpha modifiers in HSL
space so theme variations render correctly.
* Placeholder inheritance. Title/body placeholders now inherit
position, size, font family/size, color, alignment, vAlign, and
line spacing from the layout's matching <p:ph>, falling back to
the master and finally to txStyles defaults. Lookup tries exact
type|idx, idx-only, type-only, and aliases ctrTitle→title,
subTitle→body.
* Group shapes. Replaced the UnknownElement fallback for <p:grpSp>
with a recursive flattener that composes a:xfrm off/ext against
chOff/chExt to map child-local coordinates back onto the slide.
Nested groups compose correctly.
* Shape preset coverage. Added ~30 prst → ShapeKind mappings
(parallelogram, hexagon, arrows, callouts, flowchart, snipRect
family). Anything still unmapped falls back to a colored rect at
correct geometry instead of an opaque "Imported content" tile.
The presence of an <a:prstDash> child does not imply the line is dashed — PPTX uses val="solid" to declare an explicit solid pattern. Read the @Val attribute and only mark the line dashed when val is one of the actual patterns (dash, dashDot, sysDot, etc.).
Imported lines were rendering with arrowheads whenever <a:headEnd> or <a:tailEnd> existed at all, but PPTX uses type="none" to explicitly declare a plain end. Read the @type attribute and only mark the line as an arrow when it is one of the actual arrowhead presets (triangle, arrow, stealth, oval, diamond, …).

Summary
Rebrands the project from Caracas to Slidewise and substantially improves PPTX import fidelity (theme colors, layout/master inheritance, grouped shapes), with two follow-up fixes for line rendering.
