Good direction overall — the <th> → <td> semantics fix, hiding decorative icon glyphs, and adding esc_attr() are all real improvements, and replacing the ■ character with a CSS marker removes a lot of screen reader noise. I've left detailed comments inline; two of them I'd consider blocking.
Blocking
-
simcal-events-togglenow has no accessible name (default-calendar-grid.php:563). It has notitleand noaria-label, and its only content was the<i>you've just hidden — so it computes to an empty accessible name and announces as bare "button". This PR introduces a WCAG 4.1.2 failure. It also needsaria-expandedandtype="button". (CodeRabbit flagged this one too.) -
The color marker vanishes in Windows High Contrast / forced-colors mode (
default-calendar-grid.css:520). The old■was a text glyph and survived; an empty span painted only withbackground-colordoes not. Needs a@media (forced-colors: active)fallback.
Worth resolving before merge
-
em→remon.simcal-eventsshrinks the text on many themes — the opposite of the stated goal. On a theme with a 20px base this goes 13.6px → 12px. Details and a table in the inline comment. -
Scope gap: list view untouched.
default-calendar-list.phphas the same icon-only buttons (lines 217, 244, 711) with noaria-hiddenand noaria-label. Grid-only fixes leave the plugin non-compliant for list-mode users. -
The real WCAG failure on these controls is
outline: noneon:focus(CSS lines 250, 282, mirrored in the list stylesheet), which removes the keyboard focus indicator — a 2.4.7 Level AA failure. Meanwhile, note that WCAG has no minimum font-size requirement, so the 10px → 12px and 0.68em → 0.75rem changes are UX improvements rather than compliance fixes. Given the ticket title, I'd swap the priority.
Also flagged inline: esc_attr() double-escapes (get_color() already escapes) and doesn't protect a CSS context anyway — validating the hex would; the month heading isn't announced on AJAX navigation; events with no color render a black dot on mobile but nothing on desktop; and thead td may pick up different theme styling than thead th did.
Please also confirm testing with an actual screen reader (NVDA or VoiceOver) rather than automated tooling alone — an empty accessible name on a button is exactly the class of issue axe/Lighthouse catch inconsistently on icon buttons.

Follow-up to my earlier review — that submission lost most of its inline comments to a collision, so here they are attached to the actual lines. Nothing new in substance beyond the earlier summary; the detail and code suggestions now sit in the files where they apply.
Recap of where things stand:
Blocking
simcal-events-togglehas no accessible name once the icon is hidden — WCAG 4.1.2 (already commented atdefault-calendar-grid.php:563).- The color marker vanishes in Windows High Contrast / forced-colors mode (
default-calendar-grid.css:520).
Should resolve before merge
3. em → rem on .simcal-events makes the text smaller on large-base themes (css:513).
4. List view untouched — same icon-only buttons, and its nav buttons lack aria-label entirely (php:216).
5. Month changes are never announced on AJAX navigation (php:219).
Worth a follow-up ticket
6. outline: none on :focus for the nav and toggle buttons — WCAG 2.4.7, a real Level AA failure on the exact controls this PR touches (css:570).
7. Missing scope="col" on the weekday headers and no accessible name on the table (php:206).
For the ClickUp ticket: the semantics fixes here (th→td, aria-hidden on decorative icons) are genuine conformance improvements, but the font-size bumps are UX rather than compliance — WCAG sets no minimum font size. Items 1, 2, 5 and 6 are the ones an audit would actually flag, so I'd re-weight the scope accordingly.
Also worth verifying with NVDA or VoiceOver rather than axe/Lighthouse alone — an empty accessible name on an icon-only button is exactly the case automated tooling reports inconsistently.
