  Reuse _SearchBar instead of re-implementing it inline.
  The search field built here duplicates _SearchBar (Lines 177-227) but loses the clear-button affordance and drifts the styling. Hoist _SearchBar (or a shared component) and reuse it in both screens to keep behavior consistent and eliminate the copy.

  Health Connect color diverges from session_details_sheet.dart.
  This file declares _hcColor = Color(0xFF00BFA5), but session_details_sheet.dart line 11 declares _hcColor = Color(0xFF4ECDC4) — both labelled "Health Connect" but rendered in different teals across screens. Centralize this in AppColors (and remove both private constants) so the brand color stays consistent across the profile and history surfaces.

  ⚠️ Potential issue | 🟠 Major | 🏗️ Heavy lift
  Volume strings hardcode "kg" — breaks for non-metric users.
  SessionCard (line 145) and RecentSessionTile (lines 261-263) build the volume label with a literal ' kg'/'kg'. This bypasses SettingsProvider.unitLabel / formatWeight, so users on imperial units see the wrong unit and unconverted weight on every history list and dashboard recent-tile. Same anti-pattern as exercise_details_sheet.dart line 197.
  Either add an optional unitLabel/formatVolume parameter on these cards (passed by callers that already have access to SettingsProvider), or accept a precomputed volumeLabel string and let the caller format it.

  ⚠️ Potential issue | 🟡 Minor | ⚡ Quick win
  Regex-based value parsing is fragile.
  Stripping [^0-9.] to obtain numericValue and [0-9.] to obtain the suffix breaks for several plausible inputs the dashboard already produces:

  • "1.5k" → numeric 1.5, animates 0 → 1.5 instead of 0 → 1500, so the counter is meaningless for kilo-suffixed values.
  • "1,000" (locale-formatted) → numeric 1000, suffix ",", displayed as "1000,".
  • "-5" or "$100" → minus/dollar sign survives in the suffix in the wrong position.
    Prefer accepting an explicit double? animatedValue and String displaySuffix from the caller (it already knows the raw number), and falling back to plain Text(value) when no animated value is provided.

  Avoid hex literal; promote _hcColor to AppColors.
  AppColors's own header states "Never use hex literals in widget files — always reference AppColors or AppTheme aliases." profile_sections.dart defines _hcColor = Color(0xFF00BFA5) for the same Health Connect feature, and this file uses 0xFF4ECDC4 — two different brand colors for the same concept. Centralize this in AppColors (e.g., static const healthConnect = Color(0xFF00BFA5)) and reference it from both files.

  Hex literal violates this file's own contract; also missing const.
  selectedColor: Color(0x4D6C5CE7) is a hardcoded primary color with an alpha — exactly the pattern the AppColors header tells callers to avoid. It also isn't const, so a fresh Color is allocated on every theme read. Promote it to a named token (or use const Color(0x4D6C5CE7) at minimum) so the source of the value is clear and maintained alongside AppColors.primary:

  🧩 Analysis chain

  🌐 Web query: `In Dart, does `int.clamp(min, max)` return `int` or `num`, and does it need `.toInt()` before passing it to a `ValueChanged` callback?` 💡 Result: `int.clamp(min, max)` is typed as returning `num` (not `int`). The `num` base signature is `num clamp(num lowerLimit, num upperLimit)` [1], and `int`’s `clamp` return type is shown as `→ num` as well [2]. Because the static type is `num`, if you pass the result to a `ValueChanged` callback, you generally need to convert it to `int` (e.g., `onChanged(value.clamp(… , …).toInt())`). The `.toInt()` is required whenever the callback parameter is statically `int`, since `num` is not assignable to `int`. Note: there is discussion that the runtime returns an `int` when all arguments are `int`s, but the static signature historically remained `num clamp(num, num)` [3]. So for type safety, use `.toInt()` when the receiving API expects `int`. Citations:

  Keep the AI dependency abstract at the provider boundary.
  Providing GeminiAiService directly here makes downstream UI import the concrete backend just to observe AI state. Expose an interface- or manager-typed dependency from the composition root instead, so backend swaps stay localized and screens remain on the intended layer. Based on learnings: "All service interfaces must be defined in lib/services/interfaces/ and implemented by concrete services" and "New features should follow the pattern: Model → Interface → Storage → Manager → Provider → Screen → Tests".

  Handle errors from fire-and-forget readiness refreshes. Both call sites intentionally avoid blocking the UI, but neither attaches an error handler; any async failure from ReadinessManager.refresh() can surface as an unhandled Flutter error.
