65e1708c78 feat(web): mermaid diagram lightbox on click (#741)
* feat(web): mermaid diagram lightbox on click

Click rendered mermaid blocks in chat to open a zoomable full-screen viewer.
Re-renders from source in the modal with the current theme. Closes #737.

* fix(web): fit mermaid lightbox to viewport on open

Auto-scale diagrams to fill the viewer instead of opening at intrinsic
mermaid size. Reset returns to fit; zoom label is relative to fit (100%).

* fix(web): fit mermaid lightbox to device screen not inner panel

Use visualViewport for fit scale, full-screen pan layer, and a floating
toolbar so the diagram can use the whole display.

* fix(web): show mermaid lightbox by reusing inline SVG

Second mermaid.render on open often left a 0×0 SVG while fit scale was
computed from the loading placeholder. Reuse the inline SVG in the modal
and measure viewBox with retried fit-to-screen.

* fix(web): uniquify mermaid SVG ids in lightbox clone

Inlining the same mermaid markup twice duplicates element ids and breaks
url(#ref) resolution in the modal copy. Prefix ids and hrefs for lightbox only.

* fix(web): give mermaid lightbox SVG explicit dimensions

Mermaid emits width="100%" with max-width in px; that collapses to 0×0
inside the centered lightbox layer. Derive width/height from viewBox for
the uniquified lightbox clone.

* fix(web): render mermaid lightbox via isolated SVG data URL

String id rewrites broke mermaid's embedded CSS so only labels appeared
zoomed. Rasterize the inline SVG to a data-URL img instead of duplicating
markup in the DOM.

* fix(web): lightbox re-renders SVG for sequence diagrams

Data-URL images drop or blank some mermaid diagram types (sequence).
Re-render with a modal-specific id into inline SVG on a code-bg panel,
and add sequence theme variables for dark/light.

* fix(web): mermaid lightbox uses inline SVG in shadow DOM

Reuse the inline render in an isolated shadow root so sequence CSS stays
intact, and fit the viewport from viewBox dimensions instead of the loading
placeholder or width="100%" layout.

* test(web): Playwright lightbox coverage per mermaid diagram type

Add e2e harness and a script that opens the lightbox for each diagram
kind (flowchart through kanban). Fit uses inline getBBox() so compact
charts like gitGraph fill the viewport.

* test(web): bounded Playwright via webServer, fix gantt fit sizing

Playwright owns Vite lifecycle (no agent-spawned dev server). Fit uses
viewBox unless viewBox padding is excessive (gitGraph); wide charts use
width-based coverage in e2e.

* chore(web): gitignore Playwright test-results

Co-authored-by: Cursor <cursoragent@cursor.com>

* fix(web): address PR 741 bot feedback (typecheck, fit floor, gitignore)

Guard lightbox open when svg is null; allow fit scale down to 0.01 while
keeping 0.25 minimum for manual zoom; ignore Playwright test-results/ correctly.

Co-authored-by: Cursor <cursoragent@cursor.com>

* test(web): Playwright asserts click expands diagram vs inline

Measure inline vs lightbox bounding box after click; require visible
growth (area ratio or max dimension) plus dialog + shadow SVG content.

* test(web): Playwright against live HAPI session for mermaid lightbox

Add seed script for a dedicated chat session, live hub Playwright suite
(HAPI_LIVE=1), and dogfood doc. Live tests fail until driver serves shadow-DOM
lightbox (catches gray-box regression on stale bundles).

* fix(web): undo wrapper transform in lightbox fit; carry fit floor in zoom

Resolves PR #741 review threads (HAPI Bot Major):

1. measureSvgIntrinsicSize / measureContentSize prefer intrinsic dimensions
   (viewBox -> width/height attrs -> img.naturalSize) before getBoundingClientRect.
   When the rect is the only signal, divide by scaleRef.current so the 50/200ms
   refit retries stop compounding with the wrapper's scale(...) transform.
   Large diagrams no longer jump tiny or oversize after async render completes.

2. Interactive zoom (wheel/keys/buttons/pinch) now clamps with
   Math.min(MIN_SCALE, baseScaleRef.current). A diagram fitted below the
   normal 25% floor stays reachable instead of snapping back to 25% and
   clipping. Zoom-out button disabled threshold uses the same min.

3. Add Vitest coverage for both helpers (intrinsic precedence, scale-aware
   rect fallback, divide-by-zero guard) so regressions surface without
   needing the full Playwright stack.

* fix(scripts): mermaid seed refuses to wipe non-fixture sessions

HAPI Bot Major (PR #741): SESSION_ID is documented as overridable,
and the script unconditionally deletes every message for the target
session before seeding fixtures. If pointed at a real session id,
that's silent data loss.

Refuse to proceed when an existing session id has a tag other than
'mermaid-lightbox-e2e'. New ids and the canonical fixture session
still seed normally; real sessions throw before any DELETE runs.

* fix(web): normalize mermaid svg for lightbox shadow root

Mermaid emits width="100%" on every diagram. Inside a shadow root whose
host has no explicit size, that collapses to zero in Chromium for most
diagram types - only ones that ship pixel attrs (e.g. journey) happen to
render. Operator confirmed on the live driver: every diagram except
journey opened to a grey rounded square.

MermaidLightboxSvg now runs normalizeMermaidSvgForStandaloneDisplay before
injecting (strips width/height="100%", bakes viewBox dims as pixels) and
sets :host{display:inline-block} so the host sizes to the SVG. Inline svg
in chat is unchanged - only the lightbox copy is normalized.

* fix(web): keep mermaid lightbox content below the toolbar

Operator screenshot showed the diagram top (e.g. pie 'Pets' title)
clipped behind the toolbar bar. Two causes:

1. getScreenFitSize used the full viewport height, so the fit scale
   sized the diagram to fill an area the toolbar overlapped.
2. The viewport (drag/zoom area) was inset-0; content centered on the
   full viewport center, not the visible region's center, pushing the
   top behind the toolbar.

Measure the toolbar with a ResizeObserver, subtract its height from
the fit calculation (clamped at zero), and start the viewport region
below the toolbar (top: toolbarHeight). Fit scale recomputes whenever
toolbar height changes.

Adds Vitest coverage for getScreenFitSize reserved-top math.

* fix(web): guard ResizeObserver before constructing it

HAPI Bot Major (PR #741): Vitest jsdom does not polyfill ResizeObserver,
so the toolbar measure effect throws ReferenceError when the existing
mermaid-diagram React tests open the lightbox. Same code path is also
brittle in any browser/webview without the API.

Fall back to plain window 'resize' listener when ResizeObserver is
absent. Toolbar height won't auto-update on element resize without it,
but the lightbox still renders and the resize listener catches the
common viewport-rotation case.

* fix(scripts): live mermaid playwright wrapper runs from repo root

HAPI Bot Minor (PR #741): the wrapper sets cwd to scripts/, but the
test:mermaid-lightbox:live npm script lives in the repo-root
package.json, so spawning npm there exited before Playwright started.
Switch cwd to the repo root and drop the unused WEB_DIR constant.

* fix(web): accept signed viewBox values in mermaid lightbox normalize

HAPI Bot Minor (PR #741): the viewBox regex only matched digits, dots,
and spaces, so a valid viewBox with negative origin (e.g. '-8 -8 640 480')
returned null. normalizeMermaidSvgForStandaloneDisplay then became a
no-op and left width='100%', re-introducing the zero-sized lightbox
render this PR is meant to fix for the affected diagrams.

Switch to the bot's suggested regex (signed numbers, single or double
quotes, comma or space separators) and reject NaN parts. Adds Vitest
coverage for signed origins, single quotes, comma separators, the
malformed/no-viewBox null paths, and an end-to-end normalize test that
fails against the old regex.

* fix(web): align @playwright/test on 1.60.0 across workspaces

HAPI Bot Major (PR #741): web/package.json pinned @playwright/test at
1.49.1 while the root workspace and bun.lock were on 1.60.0. The
mismatch surfaced after rebasing onto upstream/main, where the root had
already moved to 1.60.0 while my web devDependency lagged from an older
commit. A frozen install would reject the lockfile and the new web e2e
script could resolve a different Playwright than root scripts.

Bump the web devDependency to 1.60.0 and regenerate bun.lock so all
workspaces share one Playwright version.

* fix(web): move mermaid playwright fixtures out of public

HAPI Bot Minor (PR #741): the e2e and smoke fixtures lived under
web/public, so Vite copied them verbatim into web/dist and the hub
asset generator embedded them in production bundles. Both pages
import Vite dev-only paths (/@react-refresh and /src/dev/...), so
the production /mermaid-lightbox-{e2e,smoke}.html routes would 404
on those imports.

Move both fixtures to web/e2e-fixtures/ to match the existing
scratchlist-fixture pattern (relative ../src/dev import, served by
Vite at /e2e-fixtures/...) and update the Playwright spec to hit the
new path. Build now ships 112 PWA precache entries instead of 114
(both fixtures excluded from dist).
