From 0bc4c16353d06513a28592da57522994255d7fc3 Mon Sep 17 00:00:00 2001 From: Xiao Yang Date: Sat, 18 Apr 2026 21:58:00 +0800 Subject: [PATCH 01/19] feat(highlight): persist highlights across commands + use outline for better coverage MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Keep injected highlights on the page until the next user-visible command (read-only follow-ups like get_tabs are excluded) so the user can see what was highlighted. Switch element borders from inset box-shadow to outline with negative offset so opaque child content (e.g. wrapping a full-bleed image) can no longer hide the border. Move labels into document-coordinate space so they scroll with the outlined elements. Single-highlight confirmation keeps the yellow "Is this the element you wanted to …" design via a dedicated DOM-injection script + canvas crop.

Sideways placements are disabled entirely because they routinely produced labels between two adjacent elements that read as belonging to the wrong one (session 444122cb: `UHT` between Fundamental and Technical tabs looked like it labeled Fundamental). When a label cannot fit above OR below its element (collision or viewport edge), the element defers to a later highlight page rather than being placed ambiguously. `total_pages` absorbs the overflow. Label fill is now an opaque darker shade of the border color so the filled badge visually separates from the bright bbox outline even when they share a touching edge. Font size reduced 16 -> 11px (height 22 -> 15px) so the badge is no taller than page body text — the labels recede into the visual hierarchy instead of dominating it.

Collision with a same-page neighbor no longer triggers a side-flip — the element is deferred to a later highlight page instead. Result: any label the viewer sees is always directly above its element, with a single exception (viewport-top elements get their label directly below). This removes the "is this label for the element on its left or the one on its right" ambiguity entirely. 2. **Tolerate 1-2 px shared-border bbox overlaps.** On finviz's filter-tab row, Fundamental (x=754..852) and Technical (x=851..928) share a 1px border at x=851..852 — a DOM rendering artifact, not a real occlusion. `bboxesPartiallyOverlap` now requires ≥ 3px on BOTH axes before treating an intersection as a real overlap, so adjacent tabs/buttons can coexist on the same highlight page. Label-vs-neighbor-bbox and bbox-vs-neighbor-label checks use strict `bboxesIntersect` (not clearance-inflated), so a label touching a horizontally-adjacent element's top edge at a shared row border is not treated as a collision — only actual pixel intrusion blocks placement.
